Parsing KML and Programmatic Data Classification

I don’t have any maps to show for this at the moment, but I am pretty excited. Thanks to reading this post by the BJØRN SANDVIK at the Thematic Mapping Blog, I finally got around to creating my own ASKMLesqu function in PHP for MYSQL. If you read anything about exporting database data to KML

3D Extrude

I have altered the formula so that elements with Z, M, and MZ values can now be parsed. I still have to figure out how google maps parses X,Y,M,Z values though. Also, I added in the ability to extrude an element from the function call. I still have to play around with these additions, but so far so good.

WKT to KML now in 3d

Alright so I have not exactly tested this with 3d data, but I’m 95% certain it will work. I decided to preg_replace out the commas and spaces instead of preg_replacing the numerical values for lat and lon. This should allow for three values per each point (x,y and z). I am still learning regex, so please pardon the hack. It looks really ugly, but it works.

 

Rocks State Park Map

This is my last weekend at Rocks State Park. As much as it will be nice to have weekends free, I am still pretty sad that the season is over. I have a lot of good memories from this summer.

So Busy

I am finally getting to the tail end of my road projections project for the Maryland Department of Planning! Unfortunately, because of this and the whole cover letter process, I am getting pretty burnt out on any other kinds of outside of work activities involving GIS.

 

Road Projections

I have officially decided to go on a bit of a hiatus on the park map stuff for a while. I wish I had time to work on that project, submit job applications and work 40+ hours, and keep my sanity. Unfortunately, I do not. However, I did do some pretty cool stuff at work last week.

 

getGeo PHP code

Over the past couple weeks I have spent some time working on the Trail Maps for Rocks and Susquehanna State Parks. I noticed that there are some errors in the php code I posted a couple months ago with regards to parsing the elevation. In the very near future I will be modifying this code further to pull the elevation value from the database.

 

Vacation

So you know when I said I would update next week and didn’t for the next two weeks. Yeah. Well, family came up for the fourth of July and I had to work a few extra days at Rocks State Park due to the holiday. The end result of these events was a slacking off on my mapping projects.

 

MYSQL, KML, and PHP

I’ve made a lot of progress in the last week with the implementation of a gis utilizing google maps as the front end and a mysql/php backend. It has taken a little work, but hopefully by next week I will have some running models on the site.
