Q: Can maps be printed?
A: Yes. You can print through your browser. Chrome users - click the 3 dots ==> print. Firefox users - click file ==> print preview.
Q: Can maps be printed to scale?
A: No. It is possible that such a feature might be added in the future but there is no schedule for doing so.
Q: I used the sidebar to add some GIS layers to a GISsurfer map. How do I save a browser bookmark for my new map?
A: In general, if you open a webpage then you can save a bookmark for that webpage. To save a bookmark for your new GISsurfer map, click Menu ==> Link to this map. Copy the link that is displayed, paste it into a new browser tab and open the map. Now you can save a bookmark for the map that you just opened.
Q: Does GISsurfer have a basemap similar to the Google hybrid basemap that displays an aerial view and street names?
A: You can make a similar looking map by turning on an aerial basemap and turning on the built-in overlay "ESRI roads and labels."
Q: How can I add a new basemap?
A: You can add a new basemap via the inline parameter or txtfile parameter. In the syntax for those parameters, substitute the word 'basemap' in place of the word 'overlay'. Look at the inline parameter in this PDF file for an example. https://mappingsupport.com/p2/help/GISsurfer-link-parameters.pdf
Q: I want to look at data hosted on GIS servers but I do not know any addresses for GIS servers. Now what?
A: Here is a PDF file with a curated list of 3,500+ ArcGIS servers. These are mostly USA-based government servers from the federal level down to the city level. https://mappingsupport.com/p/surf_gis/list-federal-state-county-city-GIS-servers.pdf
Q: I am trying to look at a GIS overlay layer and it never appears on the map. Why?
A: There are several possible reasons.
1. The zoom levels at which GIS basemaps and overlays appear on your screen are defined on the GIS server and cannot be changed by software. You might need to zoom out or zoom in. If you need to zoom in more than allowed by the current basemap, then try changing the basemap to "ESRI topographic" or an aerial basemap.
2. The symbols or lines that GIS layer puts on the map might be hard to see. Try changing the basemap to "All white basemap".
3. The ArcGIS server might be busy. Try waiting 10-20 seconds. Try tomorrow.
4. The GIS server might be down. Or the server administrator might have changed the server address or layer number. Find the https or http address for the GIS layer you are trying to open and enter that address into a browser bar to see if the table of contents appears. Check if the layer number on the server has been changed. If you are looking at the table of contents for MapServer layers, then click the "Legend" link and see what kind of symbology is used for thr data you are trying to display.
5. The overlay layer might be defined on the GIS server but no data was uploaded to the server.
6. If the ArcGIS server uses http instead of https and you are trying to display FeatureServer data, then your browser will likely refuse to display that data. This is a security feature. FeatureServer data is actual coordinates that the server streams to your browser. If that stream happens over http (instead of httpS) then the stream is not encrypted and can be hacked. MapServer data and ImageServer data will work OK over http since that data is sent from the GIS server to your browser in the form of images - not coordinate data.
Q: Some GIS overlay layers do not display if the map is zoomed in too far or zoomed out too far. Can you fix that?
A: No. The zoom levels at which GIS data displays is defined on the GIS server and cannot be changed by software.
Q: I made a map that has some GIS layers. How can I add a legend to the map so people know what the various symbols mean?
A: The GIS server that is hosting your map layers includes a 'Legend' web page that explains each symbol. When I make a map I include a "Map tips" link in the title. That link points to a web page I made that is hosted on my server. That web page includes links to the various 'Legend' pages for the GIS layers the map can display. Another option would be to make a PDF file with the legend links. Of course you would still need a way to put the PDF file online. Finally, if your map only requires a single link to a GIS legend page, then you could include that link directly in the map title. The GISsurfer 'Help' page shows how to add a title to the map.
Q: I made a map by adding some GIS overlay layers. How do I save the map I made?
A: Click Menu ==> Link to this map. The link that is displayed will replicate the map on your screen.
Q: How do I convert a Gmap4 link to a GISsurfer link?
A: 1. Start GISsurfer https://mappingsupport.com/p2/gissurfer.php
2. To center GISsurfer at the same location, click Menu ==> Search and then paste in the value of the ll parameter from your Gmap4 link.
3. Pick a basemap. The server hosting the basemap limits how far you can zoom in. I have no control over that setting. ESRI streets, ESRI topographic and ESRI aerial go to zoom level 19.
4. Maybe turn on an overlay. If you are using an aerial basemap then consider turning on the overlay "ESRI roads and labels".
5. Click Menu ==> Link to this map. Copy that link and paste it into a browser tab.

Q: Can GISsurfer display KML, KMZ or GPX files?
A: Not yet. I will take a look at adding support for those file types.
Q: I tried to post a GISsurfer map link on Facebook but the link did not work. Is there a solution?
A: Fairly simple GISsurfer links work on Facebook fine. But if you are trying to post a long and/or complex GISsurfer link then I recommend using a link shortener such as Bitly
