Beyond Accuracy and Precision We discussed the issues of accuracy and precision in last lecture, but we should also look a bit deeper at error and other related issues defining data quality. We are now well versed on how important “clean” spatial data is for mapping and analysis, but we Read more
We are going to take the lessons we learned in the Tutorials and lecture 5 to create a custom project in SMASH and collect some data. This assignment will be worth 25% of your grade for the course. It is due November 20th. Using SMASH We have played with the Read more

To get started let’s update our computers and install a python framework known as Flask that is going to get us mapping quickly! Flask is one example of a Model View Controller or MVC for short. The concept here is that we have separate components to make updates easy. For Read more
Question 1 Below is the procedure for reducing the processing time of a FME/FMW script. The point of proposing this assignment was to get an understanding of different data structures for GIS data formats. Below are the procedures for cleaning up the saf format: Unzip the .saf in 7zip of Read more
Using data from mobile phones, raster and vector data We are going to look at some GPX data (the type that comes off your phone when collecting tracks and waypoints using GPSLogger, OpenGPX, and other methods (like GPS units). We will then take it into QGIS and ArcPro to do Read more
Getting data out the hard way Why would we make anything easy for you in this course?.. We are looking at the data we bring out of SMASH in two ways. The way you may most likely bring it in if you are working as a GIS Analyst with no Read more
1. Land Use, Parcels, Streets and Districts can all be placed on top of each other in a GIS such as QGIS (as in the diagram). What is the GIS term that describes them? 1/2 Mark layers 2. What does the GIS acronym stand for – what is GIS short Read more
The Video Link for this Tutorial is:Video Link GNSS refresher Take a look at the Geog 204 tutorial on GNSS to get a refresher on how GNSS works. GNSS stands for Global Navigation Satellite System. GDAL and creating a list of raster layers I (Scott) realize windows is getting better, Read more
Outline for the Project Proposal For this course, the purpose of the project proposal is to explore, collect and organize published literature pertaining to the project you will do towards the end of the semester. This has two benefits: one is to get an understanding of the research that has Read more
