This weeks lab focused on map algebra and utilizing it provide specific outputs. Additionally, the lab introduced the topic of resampling. The idea of resampling to create less precise but more useful information for analysis. For example, without resampling you will have much more variation inf surface level and it will be more difficult to establish a surface level for analysis. The first requirement of this lab was to generate a map depicting all of the flat areas inside of the mission area. To accomplish this goal we used the aspect analysis tool and the map calculator to find the area without a slope.
Then we were instructed to find all of the areas between the elevations of 233 and 234 to have an idea of water collection.
Then we were instructed to find all the areas with a slope exceeding 30 Degrees. To accomplish this we utilized the aspect tool.
Then we were instructed to again show areas that exceed 30 Degrees but only above an elevation of 245 meters. To accomplish this we kept the aspect results from the last map and used map algebra to combine the limitations.
