Please trace buildings in Nakatsu City area

We have chosen GSI standard map for first step of our crisismapping in Fukuoka and Ohita, Japan.

This maps has "cartographic generalization" process, it means simplification for middle zoom level. We know, "GSI ortho" is more good, but little difficult for beginners for buildings tracing. GSI standard maps is more easy and speedy for tracing in whole target area, it is very large area.

Next step, we should choice aerial photo for tracing, but we are thinking, first step, we should choice GSI standard maps for beginners.

In addition, Bing imagery has no good accuracy, we have to offset with reference data. We will finish first step soon.`
