Google Maps JS Library support : geometry

January 6th, 2011 Comments off

Yesterday, there was an announcement about new supporting library for Google Maps JS API v3, which is Geometry Library.

For almost a year, I have been looking for switching from V2 to v3 and there is one missing point for enterprise level which is geometry support. With geometry support, ExtMap written in v2 will be completely convertible to v3.

The library will not be added by default, you should add some parameters to script loading url (libraries=geometry). This is also a good option to keep file size less for normal users.

This announcement also a good clue for more libraries will come to Google Maps API in 2011.

Wish you a year with more geo news 🙂

iExtMap for iOS

August 24th, 2010 Comments off

I have been quite busy with several projects and I can’t find time to write on my blog.

I have been working on a project to show different GIS services (incl. ArcGIS server, WMS and KML/GeoRSS) on iOS devices, especially on IPhone, which is named iExtMap.

iExtMap is a mobile GIS viewer for iOS (IPhone, IPod and IPad). It is a hybrid application, map part is based on Google Maps JS API v3 and other parts are native. This hybrid structure saves a lot of time during development phase. This first version is just a viewer, but I’ll add more features like identify or query in next releases.

There is also a new web site both for iExtMap and ExtMap Framework, which is

iExtMap is a free application downloadable from App Store for now and I want this remains same if I’ll find sponsors or advertisers for iExtMap. If you or your company is interested in iExtMap, please do not hesitate to contact me via alper [(at)] mekansal (dot) com

FOSS4G 2010 Voting

May 5th, 2010 Comments off

Dear All,

Last month, I submitted an abstract about the ExtMap to FOSS4G 2010. Now FOSS4G is calling for voting the abstracts. You can see 360 candidate abstracts and your votes will make the schedule.

The voting address is as follows : (deadline is May 14, 2010)

The title of my abstract is “Developing Desktop-like Web GIS Applications with HTML and JavaScript”, if you want to give a chance 🙂

By the way, I’m quite busy with a new project on IPhone which is a mapping application indeed 🙂

I’m back…

February 22nd, 2010 Comments off

After 6 months of military service, I’m back to my normal life. Especially I came back a month ago, but it takes time to get used to normal life 🙂

Anyway, military service was a big burden on my shoulders and now it is over. What about the future plans?

For now I’m planning a trip to USA for a job interview and I may change my continent within next months.

I also started to refresh my brain to get new version of Ext JS to improve ExtMap. Yes, you read correctly, I’ll continue to develop ExtMap, but this time, I will try a different way.  During my military service period, I saw some geo web applications which partially/completely uses ExtMap Framework, but they deleted credits part and sold it to their customers. I can’t understand why people are doing such things. I don’t want any money from them, just credits page.  Anyway, I’m working on that problem.

I have also plans to work on Google App Engine both for the web and geoweb, but I need time to understand the new approach to write applications on No-SQL platform. This approach may shape the scalibility of future web applications.

As a result, I’ll make a fresh start in my life and this gonna be awe…. (wait for it)….someeeeee 😀

PS : Thanks to Barney Stinson for his great catchphrases

June 24th, 2009 Comments off

I have been working on ExtMap (previously known as Summit ExtMap)  versions and its website. Today I ‘m proud of announcing the three versions of ExtMap and its website. As it is stated, I changed the name of project from Summit ExtMap to ExtMap and the versions are as follows:

JS ve REST versions are mostly the same as Summit ExtMap, but OL version has some missing features which will be done soon. The website of ExtMap is also available as

Thank you for your votes

April 6th, 2009 Comments off

Please forgive me about this late post. I want to thanks everyone who voted for me at ESRI Developer Summit Mashup Challenge.  I hope all you like the “Summit ExtMap” mashup framework and use it in your projects.

The reason for this late post is “Summit ExtMap“, because I still working on framework to add some new features. The coming release will be seperated to 3 different versions as

  • Summit ExtMap (for ArcGIS JS API Extension for Google Maps)
  • Summit ExtMapRest (without ArcGIS JS API, works only with ArcGIS REST API and Google Maps API)
  • ExtOL (Ext JS with OpenLayers supporting ArcGIS REST API)

You can choose the version suited for you. Please do not hesitate to ask for questions, new features and bugs.
