Hi, I am new to mapping and GIS apps and I find it very interesting. I have got satellite imagery/aerial photos of my town and I would like to create a street map and landuse map from these photos with mapwingis. All I have been able to do is create cont I have got satellite imagery/aerial photos of my town and I would like to create a street map and landuse map from these photos with mapwingis. It makes more sense to start with the kind of map you want. Street maps and land use maps are very different from each other, are very hard to create, and are probably already available for your area. I then use the add shape(polylines) tool and trace the roads/streets on the jpeg layer and add them to my new shapefile. It seems an image analysis issue. Did you try other GIS software like ILWIS or GRASS for this kind of question? The power of this kind of tool is to automatically convert images to classified grid (street, water, rural area, …) and then, to vector map. In this case, MapWindow seems to be too young! you are asking here too much for what can be done software wise without robbing not only one but several big money institutions. What you want is an automatic line detection and follower on aerial photos. As far as I know, not even the US military has such a tool working completely. Yes, the best way is to do this manually as you have started. After a while you will be more proficient in doing so. You could also think about getting some help from students for moderate pay. and what ever comes out of this. You will find that what you want to do automatically really is not an easy straight forward task. You will also find that aerial photos have a nasty habit: they are accurate in their own way –>, central perspective. Unfortunately that is not the same as the parallel projection basically used for maps. That means any variation in terrain height will misplace the photo content away from where it should be on a map: search for ‘radial displacment’. Although there is no converter to do the function you want, there are tricks in MW that can make your task easier. First pick the streets you want to make into a shapefile then draw one straight line from the start to the end, ignoring the turns or intersections. Then go into ‘add vector’ and add enough new vectors to the line that you will then move to their proper positions. Remember there are ‘snap to’ functions that can help you as well. Set you attributes right away add fields that will reflect any analysis you may want to perform in the future. It really helps to plan your attack from the start. From there it is a matter of patience. Good luck! I hope this helps. <,a href=’http://www.MapWindow.org/download.php’>,<,img src=’http://www.mapwindow.org/graphics/160x120_MapWindow_Button.gif’>,<,/a>, Source.
