How many times have you added a tool in a toolbar, just because the tool is there and you can do it? I guess that many more times than is really necessary.


The tendency to overcomplicate an app is directly proportional to the number of options out there . Everything is possible, in theory, when we are talking about designing apps. Why not? This is the common answer to the question "What do you think if we add....?"


But it is time to change. It is time to think the other way arround. Why not ask "What do you think will happen if we remove this tool?" I bet that many customers or users will scracth their heads, to find an answer. "mmm, weeeellll, probably Mr. Smith, will miss it. And you know, Mr. Smith is the guy who manage the GIS, we cannot remove this tool!" Well, actually we SHOULD remove this tool, for this very reason. A person like Mr. Smith, will be a GIS power user and, as such, he will have a full-featured desktop tool, with this tool alredy incorporated.


The questions then should be, "Who is going to use the app? Will this person really miss this tool?" If you have to think more than 5 seconds to find an answer, just do not add it!


Otherwise, your app may end up looking as this :


I've recently read a very important blog post from esri, "Sharing Web GIS Services? Always enable TLS". The key point is that you should ALLWAYS enable HTTPS using TLS or, if you are just using HTTP to publish web services, activate both, HTTP and HTTPS. This way, not only are you making your services more secure, but you are also, making possible to combine with other services, outside your organization, in a secure way.


By the way, the article states that SSL V3 is dead because of the "Poodle Vulnerability". And POODLE stands for "Padding Oracle On Downgraded Legacy Encryption". If you want to learn more about these two protocols (SSL and TLS) here is a short 7 minutes video:



When talking with customers about security, and how important it is for them to secure their geographical assets, you have to know what are you talking about.

I've seen this amazing video of the DevSummit conference about Vector Tiles. Please, do watch it!


What is more impressive, appart from the performance is, in my opinion, how easy is to create these vector tiles packages. You can see as well how ArcGIS Pro is going to be used by GIS professionals to create these sets of good looking professional vector tiles to create awesome maps.


The other relevant feature that I would point out, is that, apparently, every vector map loaded in PRO can be easily transformed in a vector tile in just a few clicks. For instance, if you are able to load S-56 nautical charts, these charts can be easily shared using your ArcGIS Online (I guess that tiles will be soon incorporated there too) and/or ArcGIS for Server. No need to use third party software or extensions to serve this content out anymore!


These are really good and promising news!
