Hi, See a coarse example image at http://latuviitta.org/documents/Buffer_along_route.png and imagine that your are planning your trip and you would like to have a lunch sometimes between 12 PM - 14 PM. Potential restaurants are then inside the purple buffer zone. Especially if you do the analysis while driving and being just at the 12 PM point there is a restaurant inside the search radius but which should not be selected because you do not want to turn back.
OpenJUMP has features which could make it as an extremely good navigator. - Supports both georeferences images, imagery from WMS, and vectors - With dynamic PostGIS layers with BBOX and now also with max features limit it can handle huge datasets - With filtered PostGIS layers it is possible to make tailored maps for any need There is also much to improve. - Navigator users would want routable maps. PgRouting or something might be used for that - There should be an alternative simple user interface for on-the-road use with few and big buttons - PostGIS is too heavy to learn for big audience. Improved Spatialite support could be a solution. - OpenJUMP rendering is not the best that exists and for example labels following roud would be nice to have - Many nice little things to do for many new developers, like - Automatic alerts with sound and pop-ups when entering a proximity zone of hazardous features - Automatic road data quality check/delineation by integrating the road matcher plugin with GPS plugin - Drive data logging - etc. -Jukka Rahkonen- Sunburned Surveyor wrote: > > Jukka, > > The last two (2) features you mentioned would certainly be useful.
