minus-squaremisterdoctor@lemmy.worldlinkfedilinkEnglisharrow-up32·2 年前You want an example of local depression just swing by my place anytime
minus-squareIlliterate Domine@infosec.publinkfedilinkEnglisharrow-up19·2 年前Here’s a slide describing how depressions are represented, and here is a topographical map of a sinkhole showing the hashes. That said, I had to look pretty hard for a map with those marks. Numbers are much more common.
minus-squareBCsven@lemmy.calinkfedilinkEnglisharrow-up6·2 年前Ah, awesome. i appreciate you taking the time to put this together. I dont recall these on maps, but as you said numbers are common. And i typically use the topomap with shading, so shading helps with understanding the terrain
