• 13 fixed scale map views• Search options: full postcode, place name, grid

reference• Slippy maps – click and drag• Add annotations• Measure lines and areas• Some views customisable:

– can select which features to display– can select an alternative map data display at the

same scale

• Print in PDF format - A4, A3, landscape or portrait

• Export to JSON........... Soon?

Annotations tools

• Tools to add lines, shapes, text and labels to your maps available

IWMW 2011

Annotation tools

• Toolbar appears at the top of the screen – can be moved around

• Main options to add annotations in the Draw & Create area - add:

• Add symbols, text, lines, polygons, pre-defined shapes

• Annotations remain on your map at the same scale as you zoom in and out

• Annotations appear on your PDF map print

Making a Campus Map

Confession time – at the present you cant actually do what I am about to demonstrate, but we hope to implement this soon and welcome feedback on what would be useful to web.

IWMW 2011

Theoretical process 1

1. Do some digitising – I would recommend that you theme your polygons. The colours are retained in the output so it makes it easier to re-interpret.

2. When you are happy with it, press the magic button

3. Get the code and load it into a GIS or load it into a web page through an API such as openlayers/google

Magic button may appear

here....

IWMW 2011

Practical

Onto the practical exercise

Familiarising yourself with Digimap ROAM

This should take around 30 minutes

Then we will look at what we can do with the output.

IWMW 2011

After the magic button?

Well, this is the bit has still to be decided and we want your help.

IWMW 2011

What to do next?

Now we have digitised the buildings and grabbed the GeoJSON through the “magic button” what options are there?Here we will outline 3 options:

– Google Earth– Image files as output (for print or Google Earth)– OpenLayers dynamic map

There may be other options/needs. If you have any thoughts, we would like to hear them.

IWMW 2011

Google Earth

To get the annotations into Google Earth it is pretty easy. We need to convert the GeoJSON to KML

Using the ogr2ogr libraries:

ogr2ogr –f “KML” campusmap.kml input.geoJSON

IWMW 2011

OGR2OGR libraries available through FWToolshttp://fwtools.maptools.org/

Google Earth

IWMW 2011

Case study

Campus maps for Edinburgh University

Requirements:– Make map that can be integrated into

MobileCampus App– Define all university buildings as polygons– Link to attributes– Make maps which show uni building

• Maps must be “lite” enough to deploy on mobile

IWMW 2011

Recipe – part 1

1 x IS intern

30 minute intro to Digimap ROAM

1 x copy of current campus map

1 x access to Google Streetview

2 x lunch time walks

1 – 2 days of digitising

http://www.flickr.com/photos/indieb0i/101943682/

Not mine, honest

Take intern and train on how to digitise, set intern loose and copy existing map, checking it is correct with google streetmap, Openstreetmap and ground truthing (lunchtime walks).

IWMW 2011

Recipe Part 2

• Once you have the JSON, convert to shapefile format: – Ogr2ogr –f “ESRI SHAPE FILE” campusmap.shp

input.geoJSON

• Import into GIS and theme• Add basemap• Export to desired file format (png in this

case)• Re-project png from OSGB to WGS84 for use

in google maps.

Issue with the buildings here, they are new

and don’t appear on OS

maps yet.

IWMW 2011

Doing more with GIS/OpenLayers

QGIS is a free, open source piece of software that is easy to use and well documented

We will try to get our shapefile loaded and then export it in some openlayers code that can be dropped into a webpage to give an interactive map.

IWMW 2011

Output (OSM)

• No coded written

• Can add in attributes

• Can apply styles to data in QGIS

• Works in all good browsers (so not IE)

IWMW 2011

Output (Digimap OpenStream)

• Grab the example code from OpenStream site

• Copy the variables to the beginning of the script

• Add a new OpenLayer.map to the index.html

• Discover the projections dont match• Panic!• Find someone clever• Copy their code (function proj2.js)
