I foten take the best info I can get. In your case, that is the .shp files that are outdated. Then go through and identify all the areas that are innaccurate. Then see if Google Earth has image info for those blocks. If it does, then use G.E. to trace the footprints of all the buildings. Also update any city block outlines that need to be updated. And also any road centerlines that need to be updated. Just make sure to keep everything organized well. Keep the same layers that you got from the .shp files. They probably gave you a block outline, road centerline, and hopefully bldg footprint files. So when you add your data, just follow the same scheme so that it is all organized correctly. Then you can export your block layer (or component) out as a .shp file. And same for all the other layers you have changed. To recap:
Take base .shp file info
Determine the blocks, parcels, roads, buildings that need to be updated.
Use Google Earth Images as a new base for those areas.
Just trace what Google Earth shows
Export everything as .shp files.
And that is probably how I would approach it. If there are areas that Google Earth is not current on either, you will just have to go out and measure it by hand if possible.
Thanks so much Chris,
Used older version of SketchUp (version 5 with .shp plugin) to read the shapefile, and saved it to a skp file. It shows building foot prints, and that is all. They are like a component, and I can double click on them to open them, and then right click to edit, and pull up a building. The zip file I got from the city has other files besides the shapefile. How do I read those, and glean the information from them?
Can I overlay a graphic pulled in from GE with the shapefile now turned .skp file, or the reverse so I can reference one with the other?
The city says the GIS file I recieved is all they have, and would be more then happy to get updated information, and also mentioned getting that information of GE would be accurate enough for them. Is that true? And can I export a Sketchup model out as a shapefile?
OK! The biggy Chris. Can I get you to create a plugin that could automate all of that? LOL! I heard you could!
