Using Advanced Features of the BGIS Online Maps

Advanced features are available in the BGIS Online Maps that even allow you to share your data with our Web Map Service, create Shape files and Layers.

"CLIP, ZIP n' SHIP" essentially allows you to clip a subset of the BGIS Online Maps data and download for use on your desktop using either a free GIS Viewer (Arc Explorer) or your own GIS package ArcView 3.3 or ArcGIS. The files once unzipped are in ESRI Shape format which is almost universally read by desktop GIS packages.

"SHAPE n' SHARE"

You can mark-up the BGIS Online Maps with point, polylines and polygons, store these as either session files (to store on your computer) or store on our server as handy bookmarks which can be distributed to your colleagues as a convenient email link. You can even download all of your mark-ups as zipped shape files to use on your desktop GIS.

"SECURE VIEW"

Got sensitive data that you do not want other people to use but do want to view it with our Web Map Services. Well it is now easy simply upload your Shape (.shp) and (*.dbf) and our Web Map Service will add it as an extra layer of information. It does have to be in the same projection system which in the case of the BGIS Online Maps is unprojected geographic co-ordinates (Latitudes and Longitudes based on decimal degrees). Once you have finished you can close your browser and you data is safe with you. You can even save the view of your data as our session certificate files but for security these can only be viewed on your PC.

"WAYPOINT PLOT"

Got lots of waypoints stored on your GPS? We think we have the easiest way to plot these in a GIS, that's right directly onto our the BGIS Online Maps. Save your GPS points with one row for header of information and three columns representing your ID and Latitude (Y) and Longitude (X). In Excel save as Comma Separated Value file (*.csv) and upload this file onto our Web Map Services for easy viewing.

OGC COMPLIANT

What is OGC, well it's a big thing in GIS it stands for Open GIS Consortium and has been developed to ensure interoperability between different GIS users - in brief to be able to exchange Geographical data using a common format known as Geographic Mark Up Language (GML). The BGIS Online Maps allow other OGC Web Map Services to be added to our own layers of information. We have even gone a step further and given you the ability to clip out data from our Map layers and to download it as zipped GML files.

In order to get access to all of these neat new feature plus some old favourites you must use the expanded toolbox (Standard tools red toolbox).

In the next sections we use an exercise which takes advantage of these features
