Getting a Leg Up on the Registration Process for Public Schools

It seems like the more involved I am with mapping, the more uses I find for creating maps. For instance, I recently came across an article mentioning that choice enrollment deadlines for Jefferson County public schools are nearing.

For those of you unfamiliar with the public school system here in Jeffco, each family is assigned to a neighborhood school, but you can enroll your child in any public school within the county. Sounds great huh? If your neighborhood school is ranked poorly or just doesn’t suit you, you can pick another. But here’s the catch: while the registration deadline for your neighborhood school is typically sometime in August (just before the beginning of the school year), the registration deadline for a non-neighborhood school is sometime in January, and acceptance is determined by a lottery process which is subject to available space.

Hydrogeologist Maps Brine Plume in 3D with Voxler

One of the most interesting Golden Software user stories that I have recently heard was from an independent Hydrogeologist with Anthropocene Solutions Inc. named Joseph ‘Joe’ Harrer. Joe Harrer uses a combination of vertical EC measurement and groundwater sampling tools with Voxler to perform 3D brine plume modeling. Joe is working on a project where he was hired to do a groundwater characterization of a brine storage facility where initial studies proved that leakage beneath a brine plume has caused an impact to the soil and groundwater and that the impact has been spreading with the groundwater as it migrates down gradient. Local regulations required a full assessment of the plume’s extent and a model of the potential migration of the plume.  In addition, a groundwater remediation system is presently being installed at the site. Joe used our Voxler app for the 3D modeling portion of this project.

Creating elevation contours within a house footprint from paper notes

Golden Software’s Surfer program can be used in so many applied-science industries for so many different uses, I sometimes forget that it is equally applicable to more business or art-oriented fields. I had a user contact me recently with the following request (paraphrased):

“I have a paper copy of the blueprint of a house, and on it I’ve written elevation measurements that I collected while surveying on the premises. I also have a DXF file of the floorplan of the house. How can I create elevation contours in Surfer and limit them to the shape of the house?”

Gotta Plot 'em All!

A wild Zubat appeared!

Last month was the launch of Pokemon GO, an augmented reality (AR) mobile game from Niantic, the makers of the popular AR game Ingress. I must confess I've caught the fever, but I haven't caught them all! I am admittedly not a 'gamer,' and this is my first experience with Pokemon. I'm no Pokemaster, but I have fun catching new Pokemon while walking around downtown Golden on my lunch breaks, around the park, or around Denver. I haven't tried my luck battling at any Gyms yet, so I guess you could call me a casual player.

How to show areas of overlap of two contour maps in Surfer 13

I communicated with a user recently who wanted to find the area of overlap of one specific contour line on one contour map with a specific contour line on another contour map. In his case the first contour map was temperature and the second was rainfall. He wanted to find the area where temperature was above one value and rainfall was above another value. Whether this was for agriculture or for some other purpose I’m not sure, but it got me thinking that there could be many applications for a use like this. For example, you may have a contour map of density of one endangered species, and another for a second endangered species, and you’re trying to identify high populations of both in order to create a wildlife refuge. Or maybe you have population of people on one contour map and energy use on another, and you want to find areas with low population but high energy usage so you can send conservationists into that area to notify the population of smart practices. The uses are endless!

So that said, below are the steps to determine the area where two specific contour levels on two different maps intersect. In this case, I’ll be finding the area in Colorado where temperature is greater than 12oC and precipitation is less than 50 hundredths of inches, which may indicate an area that is more prone to wildfires. The data used in this article was obtained from NOAA. January 2015 – November 2015 data was averaged and then gridded in order to produce the attached grids.
