# 2.1 First, does the Isovist_App correlate?

[Yes.](http://isovists.org/depthmap-correlations/) Key isovist field measures correlate with equivalent measures produced by DepthMapX methods, but are calculated in a tiny fraction of the time, for a far higher resolution of data points. A study demonstrating  correlation of Isovist Mean Visual Depth against DepthMap Mean Visual Depth is provided [on isovists.org](http://isovists.org/2019/02/10/does-it-correlate/).
