Firefox 4: compatability with Roam

Mozilla have just released their latest web browser: Firefox version 4.

EDINA is aware that while the majority of functionality within Digimap will work with Firefox 4, you may find that you need to restart the Roam mapping services, and sometimes their print facilities, to get them to work properly. The problem is due to the underlying software we use to make maps not yet being compatible with Firefox 4; usually after reloading everything works smoothly.

Please bear with us while we make the necessary updates to ensure that Digimap is fully compatible with Firefox 4. If you cannot get any aspect of the service working properly then please contact the help desk: edina@ed.ac.uk

VectorMap District - beta release

Ordnance Survey have recently release the next version (the beta version) of their VectorMap District product. This dataset is part of the OS OpenData package.

You can read more about the changes to VectorMap District on Ordnance Survey's blog.

EDINA will be updating the version of VectorMap District available through both Digimap's OS Collection and Digimap OpenStream. The current (alpha) version will be withdrawn completely.

There is some processing work to be done on VectorMap District before it can be available through EDINA's services. With this in mind, we aim to release the new version through Digimap's Data Download facility on Tuesday 5th April and through Digimap OpenStream by Thursday 31st March.

Facebook Poll - Which GIS?

We are running a poll on our Facebook page to see which GIS is the most widely used by Digimap users.

Go to this page to let us know which one you use the most: GIS Poll

OS MasterMap background maps

OS MasterMap data is now available to download in a rasterised (image) format from Digimap's Data Download facility. If you need an image of OS MasterMap data (for example, as a backdrop map) but don't need the complexity of the original vector data, this new stuff is for you.

OS MasterMap – detailed but complex

OS MasterMap is the most detailed product offered by Ordnance Survey. Maps made with with OS MasterMap have been available through Digimap's mapping facilities since 2007, but if you wanted to use OS MasterMap as background for a customised map by overlaying your own data in a GIS you needed to download and convert the raw GML data. If all you want is a detailed colour background image, this seems like a significant investment of time.

Rasterised OS MasterMap - images not data

Digimap now offers OS MasterMap as .tif images at two scales: 1:1000 and 1:2000 through the usual Data Download facility. This saves you having to download, convert and import the data using specialist GIS software.

Where do I get the OS MasterMap raster background maps?

Log in to Digimap's OS Collection, go to Data Download and select which scale of OS MasterMap image you want from the list of products. The images are tiled in 1km square tiles, so you can select your area of interest, and the tiles covering it, in the same way as other tiled datasets.

The scales are determined according to the distance on the ground represented by each pixel. The larger scale images are based on a measurement of 0.3125m per pixel. The smaller scale images are based on a measurement of 0.625m per pixel. These equate to approximate scales of 1:1000 and 1:2000 respectively, although these are dependent on the screen resolution of your monitor. You can easily display the maps at other scales, but some loss of image quality may occur if you do.

"How To" Videos on YouTube

We have created some "How To" video clips and put them on YouTube for everyone to view. They show how to carry out various tasks with Digimap's online maps and downloaded data.

You can see all the videos on the EDINA Digimap YouTube channel: http://www.youtube.com/user/EDINADigimap

If there are any particular aspects of the service for which you would like us to make a video, you can add them to the discussion on our Facebook page or email us directly at edina@ed.ac.uk.

Updates to historical maps in Historic Digmap

On Tuesday 1st March, EDINA will be updating the metadata for the historical maps in Historic Digimap. The metadata changes will affect only the Scottish County Series maps and will mean that some maps will appear to “move decade”. More details of the implications of these changes are given below.


Accuracy of publication dates

When the maps were originally scanned, the detailed marginalia on the original paper map sheets was not captured at the same time. The marginalia contained information such as the survey year, publication year, re-publication year (if applicable) and surveyor name. During the digitisation process only one year from the marginalia was recorded; it is assumed this was the publication year but there was always some uncertainty around this.

A joint project between EDINA and the National Library of Scotland (NLS) was undertaken to digitise the marginalia of the original paper copies of the historical maps held by NLS. The metadata captured included the Survey Year and Publication Year. Until now, the survey year of all maps in Historic Digimap was unknown. We now have the survey year for a significant number (but not all) of the County Series maps for Scotland at both 1:2500 and 1:10 560 scales.

The significance of this project to Historic Digimap is that we can now use the more accurate and reliable publication dates for many of the County Series maps to improve the mapping and download facilities offered. In order to make use of the new NLS publication dates, these were matched with the original metadata using a series of rigorous database queries and manual processing.



How many maps have changed?

Consequently, around 35,000 County Series map tiles* (18%) now have survey years. Of these, around 28,000 tiles also have a more accurate publication date. In the majority of cases (over 70%) the publication date has only changed by a year or two. For nearly 2,000 tiles the change in publication date is more than 10 years, with the largest single change being 39 years. For those tiles which have not had updates to the survey year, the Landmark publication year used remains unchanged.


So what does this mean for Ancient Roam and Historic Download?

Nothing has changed in Historic Download in terms of how historical maps can be found and downloaded, but the updated publication dates will be reflected in dates provided on the order summary page in the downloader. These will be more accurate and reliable than previously.

For Ancient Roam, there are some more significant effects. The publication date is used to determine which maps are visible in each decade given in the timeline along the top of the map screen.

Many of the maps for which the publication date has changed by one or two years will remain within the same decade and therefore will not be affected. However, for some maps a change of a year or two in the publication date may be enough to shift the map from one decade to another. For example, a map previously thought to have been published in 1889 but now known to have been published in 1901, originally appeared in the 1890s decade but now appears in the 1900s decade.

Where there have been more significant changes in the publication date some have resulted in entirely new decades being available in the timeline for particular areas. For example, in Forfarshire there were two County Series editions in the 1890s. This was because maps originally published in the 1860s and 1870s were re-published in the 1890s. So where no maps appeared for Forfarshire in 1860/70s, they do now!

Other maps with significant publication date changes tend to be odd outlying tiles that for some reason had a significantly different date from neighbouring tiles. This means that some odd ‘holes’ have been filled.


How do I find out the map date source?

In addition to the new survey and publication data information, the Map Details information box will also be updated. A new icon has been added to the tool bar to access the map information and the information box styling has been updated in keeping with the other Digimap Roam clients. Three new attributes have been added to the Map Details information: Year Surveyed (where applicable), Sheet Title (where applicable) and Date Source. The Date Source information will tell you whether the publication year came from the original Landmark data or the NLS metadata.

While these changes to Scottish County Series maps means that the per decade classification is now different, the changes mean that the dates are now more accurate. Our thanks go to the National Library of Scotland for their hard work on this project.



The updates to Historic Digimap will take effect on the evening of 1 March 2011.

*Map tiles refers to the ‘cookie-cut’ National Grid versions of the maps, not the original County Sheets

Digimap Training in Leeds 23 February

EDINA is running Digimap training at Leeds Metropolitan University on Wednesday 23 February 2011. Training is free and available to support staff, teaching staff and site representatives. This course will cover an introduction to Digimap's Ordnance Survey Collection, including mapping facilities and downloading data.

For further information on the course and to book online, please read the EDINA website here:
http://edina.ac.uk/events/courses/geo/2011-02-23-digimap_collections_training.html

Digimap OpenStream Updated

Digimap OpenStream, EDINA's new open WMS service, was been updated with the latest version of MiniScale from the OS OpenData collection on 25 January 2011. The most significant changes to this dataset include improved ferry route labelling and a different representation of urban areas.

EDINA aims to provide the latest version of OS OpenData via the OpenStream service. This means that datasets may be updated part way through an academic year.

MasterMap Download: 4-7 February 2011

Work being undertaken by the University of Edinburgh will affect the availability of Digimap's MasterMap Download facility from Friday 4th to Monday 7th February 2011.

MasterMap Download will be unavailable from 4pm on Friday 4 February until 12 noon on Monday 7 February and will continue to be at risk for the remainder of Monday 7th. We would encourage anyone wishing to take data for use the following week to take it prior to Friday 4th February.

While the maintenance work may be completed over the weekend, there is further software maintenance to be undertaken by EDINA following the University's works. Currently it is difficult to estimate the length of time this will take, which is why MasterMap Download should be regarded as "at risk" for the remainder of Monday 7th February.

Marine Roam Free Trial

We are currently offering free trial access to the new Marine Roam facility to institutions which do not yet subscribe to Marine Digimap.

Marine Roam provides the only available online mapping tool for Hydrospatial data, a comprehensive dataset of features found in the marine environment, including buoys, wrecks, windfarms, sandbanks, flora and fauna, as well as transportation and socio-economic use information. Marine Roam is currently available as a beta service.

OpenStream and the GeoVation Challenge

Ordnance Survey is currently promoting the GeoVation Challenge with a particular emphasis on the use of OS OpenData. EDINA's Digimap OpenStream service, providing access to a Web Map Service (WMS) offering OS OpenData products, is available free of charge and can be used to enter the GeoVation Challenge! You just need a .ac.uk email address to register online. Read on for details of the innovation awards funding and prize money.
The current Challenge is "How can we improve transport in Britain?" Check the GeoVation Challenge website for further details. The challenge is open until 12.00 noon on 11 February 2011. If you have a great idea that uses geography to address the challenge, you could win a slice of £150,000 to help make it happen, funded by the Ideas in Transit project. There is also a share of £10,000 for the idea that demonstrates the best use of OS OpenData. The Challenge is open to UK residents 18 and over.

Revamp of Digimap Help pages

We have implemented a new Help system for the Marine and Geology Digimap collections (Marine Help and Geology Help ). The Help pages have been moved to a new production system which will make is easier for us to keep them more up to date and allow you to find the information you are looking for more easily and print better looking pages.

Visually there is not much change to the pages but over the coming months we will be updating and revising the content of the Help pages within Digimap to provide users with improved access to information about the Digimap facilities, the data available and how to use the data in different systems.

If you have any comments about the new Help pages or suggestions please let us know.

Tip: if you want to search for a phrase put it in quotes e.g. "zoom to position"

ESRI/Chest Technical Event - 23 September, London

The following event may be of some interest to Digimap users. Posted on behalf of Eduserv Chest.

---

The Chest Agreement with ESRI expires on 31 July 2011. Some of you may remember helping to shape the current Chest Agreement and how tricky it was. We're starting work on the renewal early, with a break-out and discussion session at the Eduserv & ESRI Event for Higher Education on Thursday 23 September 2010 at the Congress Centre in central London.

This event follows on from the success of two previous technical events, held at the University of Leeds in 2008 and University of Birmingham in 2009. The meeting is intended to bring together people from universities who are either using ArcGIS or other ESRI software or providing and supporting ESRI software in their institutions.

In addition to the very important session on shaping the new Chest Agreement, this year's event will also feature sessions on:

* What's new in ArcGIS 10
* How to get the most from Virtual Campus
* Mobile GIS best practice
* User presentation from University of Worcester.

Most of the presentations will be by people from within the Higher Education community. The event will also include a free (optional) networking breakfast for both users of GIS and those who licence the software to share experiences and discuss challenges. Lunch is also included.

This is a completely free event.

2010 Annual Data Update and New Data

On 31st August, the annual update available through Digimap's Ordnance Survey Collection will take place. A number of data and service changes will take place.

The annual data update applies to the following datasets:
- MasterMap Topography and ITN Layers
- Meridian2
- 1:50 000 Colour Raster
- 1:25 000 Colour Raster
- 1:10 000 Raster
- Strategi
- 1:50 000 Scale Gazetteer
- Code-Point with Polygons
- Boundary Line

NB: Ordnance Survey do not provide regular annual updates to Land-Form PROFILE and do not update Land-Form PANORAMA)

Updated data will be available in all the Digimap OS Collection mapping and download services.


New dataset

During the annual data update, a new dataset will be added to Digimap's Ordnance Survey Collection. OS VectorMap Local is a 5 x 5km tiled vector dataset, offering detailed national mapping. The data is derived from OS Landplan and is supplied in GML format. It is commonly used as a rich backdrop map to add context to user datasets. Features include roads, railways, vegetation, boundaries and buildings. Pre-defined stylesheets are available to apply to the data, or you can select and style different features in different ways to provide geographic context to your information. OS VectorMap Local will be available to download from the Data Download facility within Digimap's OS Collection.

As OS VectorMap Local is provided in GML, it needs to be converted to proprietary data formats in order to be fully utilised. Rolta UK (www.rolta-europe.com/osvector.html) have developed a free-to-use data translator tool to convert OS VectorMap Local to ESRI Shapefile and MapInfo TAB formats. Rolta also supply styling which can be applied to Shapefiles using the Layerfiles provided with the software. Styling can be applied to TAB files during the translation process. Further information about OS VectorMap Local, translation and use can be found in the Digimap Help Pages.







Ancient Roam

The 31st August update will see Ancient Roam move from its Beta phase to become a full service. Ancient Roam has proved very popular since its release in April generating in excess of 300,000 screen maps in four months. On 31st August, the ability to view two maps side by side to compare changes over time will be added. The 2up View provides a quick and easy way to view two maps from different decades at the same time.



A new drag to zoom tool will also be added to make it even quicker and easier to zoom quickly into your area of interest.

There are more features planned for Ancient Roam over the coming year, so please send us your comments and suggestions if you would like to see anything particular added. Although Ancient Roam is becoming a full service, the exiting Historic Mapper will remain until the end of 2010.


OS OpenData in Digimap

Some data products offered through Digimap have been released by Ordnance Survey under the OS OpenData scheme. Many of these were already available through Digimap and continue to be provided as before. Three of the OS OpenData products have not previously been available through Digimap. These are:
- OS Street View,
- OS VectorMap District
- OS VectorMap District Raster

All the Ordnance Survey products are available to download from the Data Download facility in Digimap's OS Collection.

Digimap continues to offer full flexibility in identifying and downloading the data you want. Although the OS OpenData products are available from Ordnance Survey's website directly, search and select options are limited.

If you have any questions about these changes or about Digimap in general, please do not hesitate to contact the EDINA Helpdesk on edina@ed.ac.uk

3 August Hardware Upgrade

On Tuesday 3 August 2010, all Digimap Collections will be unavailable from 10.00 hrs until 16.00 hrs while the service hardware is upgraded. Notice of progress will be posted on the Digimap Collections login page.

Data Usability - request for help

EDINA has been asked to post the following request for assistance regarding the usability of geographic information. Please follow the links below if you can help.

---

Hey Everyone,

My name is Michael Brown; I'm working with the University of Nottingham in conjunction with Ordnance Survey to develop a set of User Centred Design Tools for use with Geographic Information.

As part of this I am currently working on a questionnaire for the measurement of the Usability of Geographic Information. The next stage of this process is to validate the questionnaire by getting people to complete it, focusing on a few specific products. This will allow me to calculate how well it differentiates between different GI data sets as well as providing useful information about the products that will be fed back to Ordnance Survey.

I'm focusing this validation on 3 products.

1. OS MasterMap- Topography: http://www.surveymonkey.com/s/OSMMtopo
2. OS MasterMap- Imagery: http://www.surveymonkey.com/s/OSMMimagery
3. OS 1:50,000 Scale Colour Raster: http://www.surveymonkey.com/s/50kRaster

If you have any experience with any of these products, I'd appreciate your help. Please follow the relevant link(s) and complete the questionnaire(s). This version is fairly short and should take less than 5 minutes to complete.

Feel free to complete more than one of them and please forward this on to anyone you think might be able to help me collect responses. If you have any questions, please feel free to contact me at: michael.brown@ordnancesurvey.co.uk

Thank you for the help

Michael

Geology Roam - new mapping tool

EDINA has released Geology Roam; a new mapping facility within the Geology Digimap Collection. Geology Roam is based upon the Roam mapping facility from Digimap's OS Collection and includes standard features such as fixed scale map views, 'slippy maps', map content customisation, searching by place name, postcode and grid reference, bookmarking and comprehensive help.

Geology Roam contains BGS DiGMap-625, DiGMap-250 and DiGMap-50 geology datasets and Ordnance Survey backdrop mapping. The geological data includes bedrock, superficial deposits, mass movement and faults.

Key features of Geology Roam include the ability to decrease/increase the opacity of the geology data over the Ordnance Survey back-drop map. A single click on the map will query the geology data and display details about the bedrock and any superficial deposits found at that point.

Geology Roam features a new printing interface that will become standard in all the Roam mapping facilities across Digimap. The new printing interface enables you to resize and reposition the map, and to add a map title and National Grid lines.

Beta Service
Currently available as a BETA service, we encourage you to give us feedback on the usability of Geology Roam so that issues you raise can be factored into ongoing development over the coming months. As well as responding to any issues you report, the following additional functions will be introduced:

• Geological area (polygon) highlighting when clicking to obtain feature information, to make it easier to identify the extent of any geological feature to which the reported information corresponds.


• Map based links to a Geology Photography Collection (JIDI Images). Icons will appear over the geology maps to indicate the availability of geological feature photographs for that location. Click on the icon to view these photographic images within the Geology Roam application.


• Introduction of the BGS Rock Lexicon as an Independent application Geology Roam will run in parallel with the existing Geology Mapper during the Beta phase, after which Geology Mapper will be withdrawn (Dec 2010).

The existing mapping application will be withdrawn in December 2010 and will be wholly replaced by Geology Roam.

EDINA would welcome feedback on the service and on these proposed developments. Please contact us on edina@ed.ac.uk or 0131 650 3302.
