Head's up! As a result of browsers pushing for more internet security (a good thing), I am going to convert the domains I own from HTTP to HTTPS.

Hopefully this coming week I will be able to convert mappingsupport.com (Gmap4). All the existing http links to Gmap4 will still work. Your browser should automatically shift to https.

After the conversion takes place, you will see a new Gmap4 version number in the lower left corner of any map.

I do not presently know if the embedded Gmap4 maps here at Oregon Hiker will still work. My plan is to first convert a domain I own that only has ‘test’ content. Then I will run some experiments after which I will know more.

One thing I already know is that starting with version 50 Chrome will no longer support browser geolocation for web pages that use http. Since this is an important feature of Gmap4 (Menu ==> My location) it is obviously time for me to convert to https.

For anyone else with a website that is pondering doing a similar conversion, here are the two most helpful resources I have found.

1. https://https.cio.gov/
All federal websites under the executive branch are expected to converted to https by the end of 2016. This website has current ‘best practices’ for doing so. They have produced two videos that I found quite helpful. The first one is non-technical and, in part, makes the case for why all websites should convert to https.

Video part 1 - Intro to HTTPS
https://www.youtube.com/watch?v=d2GmcPYWm5k
"Pervasive monitoring is an attack"

Video part 2 - Implementation
https://www.youtube.com/watch?v=rnM2qAfEG-M

2. https://letsencrypt.org/
This is a relative new group that offers free certificates. They are on github at:
https://github.com/letsencrypt/letsencrypt

The Gmap4 National Forest Recreation Map has just been updated.

The new layer “FSTopo_download” will let you download FSTopos in the form of GeoPDF and/or GeoTiff. For more information, please click “Map Tips” in the upper left corner, scroll down and click “About FSTopo download”.

Also, for many forests (but not all) the “Trail_class” layer will show you at a glance whether you are looking at a main trail or little more than a bootpath. To get the most benefit from the trail data this map can display please click “Map Tips” and read “About trail data”.

Looking for the Map legend? Click Map Tips ==> Legend.

I am always happy to answer questions but do request that you start by reading the Map Tips since that information answers many common questions.

Is it possible to use Gmap4 as a pseudo-Panoramio? To place a marker overlay with geolocated photos? Panoramio is dead and the Google Maps/Photos combo is pretty terrible.

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 clicked.

But since this would work with *any* geotagged pic that can be viewed via a hotlink (i.e. no login creds required), I am not certain doing so would be a good idea.

Think of sensitive areas that would more likely get trampled if it was easy to see exactly where a pic was taken. There also may be personal safety issues if someone who is stalking you can easily get your coordinates from a pic you just posted online. Perhaps thoses issues are at least part of the reason Panoramio went away - I have no clue.

You can already make a Gmap4 map with symbols that are linked to pics. But it does take a bit of work. See starting at the bottom of p.15:
https://mappingsupport.com/p/help_files ... d_data.pdf

Now that I rained on the Panoramio idea, here is a teaser for what I am working on.

At last count there were approximately 1.2 bazillion layers of public-facing GIS data layers. I am well underway in cranking out code to let you start Gmap4 and then surf GIS data on any public-facing ArcGIS servers almost as easy as you surf the internet.
