OpenCycleMap in Indiana


A number of aerial and satellite imagery layers are available in iD, Potlatch, and JOSM. The default layer in iD and Potlatch is Bing Aerial Imagery, which you should generally avoid due to its age. Maxar imagery is generally the most up-to-date. Mapbox imagery is of high resolution in the Indianapolis, Chicago, Louisville, South Bend, Fort Wayne, Lafayette, and Evansville areas. IndianaMap orthoimagery is the best orthorectified and of highest resolution in many counties. Check the vintage of an OSM feature before remapping it based on older aerial imagery – a lot can change in a year or two. To keep other mappers from "reviving" a demolished building, change its building=* tag to demolished:building=* instead of deleting it.

When mapping a tall building or a road in a hilly area, choose a well-aligned, high-resolution layer to draw the building footprint with minimal skew or offset, then switch to the most current layer to look for any additions or demolitions that may have taken place recently. When mapping in a wooded area, choose a leaf-off layer so you can easily see through tree cover.
