Remote sensing with Land Cover Classification

 LULC Classification and Ground Truthing

In this exercise, we are using imagery located at Pascagoula, MS, to digitize the land cover surrounding the area and classify it by land use and description. 

In order to do this, I decided to use a land cover legend to digitize the different land types using a polygon feature class. The different land types were given different colors to differentiate the symbology of the land cover. 



I then used 30 sample points called "truthing points" to test the accuracy of my land cover results. I simply dropped 30 points on my image and then exported them to google earth using a kmz tool. I then zoomed in on each sample point and viewed the google Earth Image in 3D to see fi my land cover was classified accurately or not. I then coded my results in my truthing feature class to identify which points were accurate and wh9icvh ones were not.

The final map below shows the sample points in accuracy in comparison to the classified Land Cover...

TIN's vs. DEM's: 3D Elevation Models In Arc GIS Pro

 Elevation Models For GIS Today we are going to run through some analysis of comparing Digital Elevation Models (DEM's) to Triangular Irregular Networks (TIN's) using Arc GIS Pro.   One of the main differences between TIN's and DEM's, is that a DEM file is raster based, whereas a TIN elevation model is vector based. In GIS, we can use TIN's and DEM's to analyze elevation of local areas or global even to conduct slope analysis, aspect ratio, terrain mapping, and solve complex problems.  Using a DEM to Develop a Ski Run Suitability Map In the example below, we are identifying where an engineering firm would place a ski run for a resort in an area based on elevation, slope, and aspect parameters. We used the weighted overlay tool to combine 3 reclassified rasters of elevation at a high altitude, slope at a high pitch, and aspect for a SW positioning with given percentages of weight.   25% aspect  40% elevation  35% slope This was our result: As you can see, we c

Laying a Transmission Line in Southwest Florida https://arcg.is/1rWWj0 Story Map located at link  above https://drive.google.com/file/d/1apwrzjN_4JMhQCrrX17Cd1S3pF6W4FT9/view?usp=sharing Transcript for project located at the link above https://arcg.is/1azbO41 Web-map located at the link above A transmission line must be constructed and installed between the Manatee and Sarasota Counties, located in southwestern Florida. This project's objective is to provide electricity to the community east of I-75 for residential and commercial use. Depicted below is a cartographic model to solve this complex problem. The Transmission Line product Deliverables For the first part of this project, the homes that are within proximity of the preferred corridor were identified. A 400 Ft. buffer range outside of the transmission line corridor was used with the buffer tool. Aerial imagery was utilized to identify homes within the corridor or within the buffer ring, which are depicted below in red and or

Isarithmic Mapping: Annual Rainfall in Washington

  Isarithmic Mapping Today we are going to talk about Isarithmic Mapping! This type of mapping is a way to explain smooth or continuous phenomenon such as a heat map, weather, temperature or rainfall.  There are two types of these kind of maps, Isopleth and Isometric . .. Isopleth Maps : These are made from perceptual poi nt data such as the population of an area or the rate of crime in an area. These maps should be normalized if using raw data and should come from averages, densities, and ways to standardize the data. Such as the number of Covid cases per every 10,000 people, rather than coloring polygons of counties based on the number of covid cases.  Isometric Maps : These come from true point data, such as crime locations as points at a certain address or X and Y coordinate The two rainfall maps of Washington below are Isopleth maps as they are using perceptual data of areas regarding their average rainfall in the state of Washington. This data is already standardized due to cal
