Re: Gmap4 - Enhanced Google Map viewer with topographic maps

So I hinted at running my own TMS server and the point of this is that there aren't really any good national lidar based contour/hillshade maps out there. This is something that I want to create. Essentially the best maps for SAR, hiking, field work. Anyone in? We just need a bunch of servers and a...

Re: Gmap4 - Enhanced Google Map viewer with topographic maps

Everybody was "squeaking in for free" up to 25,000 Google map API downloads/day.

Re: Gmap4 - Enhanced Google Map viewer with topographic maps

Last week Google announced a major price increase for all maps that use the Google Map API (Application Program Interface). This includes Gmap4 and other popular browser-based map apps. Each time a map is opened, the API code is downloaded from Google’s servers to the user’s browser. The bottom line...

Re: Gmap4 - Enhanced Google Map viewer with topographic maps

Negative: I couldn't find the Legend view, which is pretty important for many of these maps. Also it seems slower than ArcGIS Online, though it's probably not a fair comparison as they may be the back end service for the data. Near the top of the sidebar is a link to that same 'table of contents' p...

Re: Gmap4 - Enhanced Google Map viewer with topographic maps

Genuinely I appreciate your providing a free service to accomplish useful things. However as I cannot use your Gmap4 in my browser of choice I wonder: what does this new feature of your map do that ArcGIS Online map viewer , which does work in my browser, does not? I wish I could answer that but I ...

Re: Gmap4 - Enhanced Google Map viewer with topographic maps

There is a major update to Gmap4 in the works. If you would like a sneak peek, I have posted beta code. Just remember the rule “No commercial use”. This new feature lets anyone surf data that is hosted on GIS (Geographical Information System) servers almost as easily as you surf the internet. Better...

Re: Gmap4 - Enhanced Google Map viewer with topographic maps

Interesting idea! I do not know what features Panoramio had so I cannot say how easy/hard it would be to replicate those features. In broad stokes, I can write code that would read the latitude longitude from a photo's metadata, display a marker at that spot and display the photo when the marker is ...

2017 wildland fires - Debris flow and landslide risk map

The USGS has a GIS server with various layers showing the risk of debris flows and landslides after the 2017 wildland fires. This map opens at the fire in the Columbia Gorge but you can drag it to other fires. To see the map legend please click "Map tips" in the upper left corner and then the "Legen...
