Remote Sensing Now Used for Landslide Mapping

Remote Sensing is now used for landslide mapping. Traditionally, a field survey would be conducted to assess and map landslide. However, depending on how large the area is where the landslide occurred, the process could become very difficult and expensive. With technology advancing every day, remote sensing is now capable of replacing field surveying because it is easy to use and allows operators to access areas that are otherwise inaccessible. What Satellites work best? Some satellites that work best are Landsat 7, Terra, QuickBird, Envisat, and SPOT. How many methods are used and what are they? There are 6 different remote sensing techniques used in landslide analysis; Optical VHR, SAR, GB

My Passion for GIS and LionMapperTeam-Enugu Campus

It is a privilege to be a member of LionMappersTeam-Enugu Campus because it is a platform where I can contribute to a global mapping initiative and humanitarian service that helps respond to resilient communities. It also gives me the opportunity to show my skills and talent, already acquired before gaining admission to study Geoinformatics and Surveying at the University of Nigeria, Enugu Campus. I had a life which introduced me to GIS early and I was able to produce a map at my previous school (AIFPU) showing all the natural and artificial features. I have always had a self-driven passion for GIS which is engraved in my heart. I was so excited when our Team Leader and Mentor, Victor N. Sun

The Smart Campus Project

Jovenes Mapeadores, the YouthMappers chapter of the University of Panama, took on the initiative to implement the Smart Campus project that will share information about all the facilities located within the UP campus to benefit the university community. It is important for people to know the different access points the university has for people with disabilities. It is important for people to know the infrastructure of university buildings for the purpose of improving them and giving them maintenance. The result we hope to achieve with this project is that the university community and people who do not know the university campus, are able to obtain updated information about the facilities of

Mapping for Better Preparedness and Flood Resilience

In a world where you can make phone calls from your watch and donate rice to the hungry by knowing vocabulary words, it's easier than ever to make a difference. Sometimes it can seem like all doom and gloom - sea levels are rising, the United States faced a record number of "megadisasters" in 2017, and temperatures in Jacksonville, FL were colder than those in Anchorage, AK. The good news, is that technology gives us the chance to help the world without having to un-bundle from blankets, dig out from under snow, or even take a shower (it's not too good to be true, promise). One of the environmental challenges facing communities across Africa is the threat of flooding. Lots of communities are

Using Open Data to Study Voting Efficiency

During GIS Week 2017, I proudly presented my group’s poster focused on gerrymandering for an applied GIS course. Gerrymandering is when one political party redraws voting districts in a way that favors them over their opponents. It’s unconstitutional, but difficult to prove in court. Rather than studying which political party was gerrymandering, we wanted to see if the voting being conducted in congressional districts did indeed have parity. In order to do so, we discovered a mathematical formula known as the Efficiency Gap. What this formula does is calculate the amount of ‘wasted’ votes in any given election. For example, party A has 100 votes and party B has 50. However, for A to to win a
