no really I mean it, they’re dead.
We (The GIS community) have spend millions of dollars on planimetric data -For good reasons too, When we were building GIS in the late Nineties, we needed help getting it going. The ASPRS had a place of reverence and stature. How many presentations begin with the person touting their resume about how they cut their week on a XJ Stereoscope 9000 – or whatever. I have plenty of friends that have made a career on providing wonderful planimetric data and that’s great. However, I see this as a new time for new technology with new needs. This isn’t 1998 any more with your ArcINFO tiles. Seamless, fast and accurate maps across county boarders are what customers require. Users don’t care about your committee meetings and RFPs.
Think about it: What are the reasons for planimetric data?
- Contours? – Create your own with LiDAR.
- Buildings? – Microsoft just released them Across the US. (File GDB)
- Lakes? – USGS Data Download.
- Sidewalks? – Open Street Map.
- Road-width? – Buffer a Centerline.
- Impervious surfaces? – LiDAR & Multispectral imagery.
- Updates? – Change detection software with machine learning.

Arguing accuracy and precision here has it is place and I would tend to agree with you. Microsofts buildings themselves are derived from LiDAR and buffering a centerline has its obvious faults. Here’s a reality check. People don’t care. We want reality in movies, there’s quite a bit of grace in cartography. The world that we live in now (especially in Illinois) is to do more with less and faster, if you can’t get it, just use a basemap form Esri, Google or Mapbox. Drones & SaaS allow us to create great (Albeit not orthorectified or certified) planimetric data for smaller areas in a matter of minutes not weeks or worse, 6 months. I’m fairly certain that if a resourceful GIS professional, not even a GISP ;p could take about 8 hours of searching and downloading and have a fairly complete offline map with data freely available.
I am not trying to make anyone mad here, this is just my view of GIS from the corn.
