Erdas Imagine & Land Cover Classification

 Remote sensing with Erdas Imagine



Today's exercise involved me using Erdas Imagine for the first time, which was pretty cool! 


Erdas Imagine is a remote sensing software program similar to a lot of other imagery analysis software programs, such as remote view and QGIS. Today, we were able to view different types of satellite imagery from LANDSAT of multispectral imagery and different resolutions. We also were able to change the colors of the different bands of our image to identify features better such as vegetation and water in our land cover. 


We start with a near infrared color scheme, making the vegetation look red in color for the forests and tree areas. 

In the image, below, we changed our colored bands to the RGB or red, green, blue color scheme to have a more natural look in which helps us identify the different land features. I then added a new field for area, and calculated the area for each type of land classification in hectares. This allows use to then export our raster into Arc GIS Pro, to then create our map and change the colors on the symbology based on a unique value classification method.

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
