The document discusses using Digimap ROAM to create campus maps that can be exported and used in other applications. It provides steps to familiarize oneself with Digimap ROAM, digitize buildings on campus maps, export the data as GeoJSON, and convert it to other formats like KML for use in Google Earth or dynamic web maps using OpenLayers. Examples are given of creating campus maps for the University of Edinburgh.

41. 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

42. Theoretical process 1 Magic button may appear here.... IWMW 2011 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. When you are happy with it, press the magic button Get the code and load it into a GIS or load it into a web page through an API such as openlayers/google

43. 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

44. After the magic button? Well, this is the bit has still to be decided and we want your help. IWMW 2011

45. Theoretical process 1 Magic button may appear here.... IWMW 2011 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. When you are happy with it, press the magic button Get the code and load it into a GIS or load it into a web page through an API such as openlayers/google

46. 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

47. 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 FWTools http://fwtools.maptools.org/

48. Google Earth IWMW 2011

49. 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

50. 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

51. 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. IWMW 2011

52. Edinburgh Central Campus IWMW 2011

53. Kings Buildings IWMW 2011

54. Western General Hospital IWMW 2011

55. Easter Bush Issue with the buildings here, they are new and don’t appear on OS maps yet. IWMW 2011

56. 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 . http://www.qgis.org IWMW 2011

57. QGIS main screen Add vector layer Layer list Map Window IWMW 2011

58. Plugins IWMW 2011

59. OGR2Layer Set an output folder Set map size IWMW 2011

60.

61. 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

62. 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) IWMW 2011
