Learn how to download a digital elevation model (DEM) after NASA retired the older global DEM and how to download the newer higher-accuracy DEM from the NASA site.
Create an account and log in to access the digital elevation model, then search, select your area, and download all data for the project.
Learn how to mosaic digital elevation models from USGS in ArcGIS, configure 16-bit datasets, set projections, and prepare a watershed for groundwater potential zone analysis.
Identify the study area's UTM zone and reproject data to UTM zone 43N in ArcGIS, export with the correct spatial reference, and attach the projection for watershed analysis.
Compute flow direction and flow accumulation using a digital elevation model to generate watershed and stream networks, manage outputs, and anticipate processing time.
Generate drainage lines in ArcGIS by converting lines to vectors and applying input flow direction. Identify a watershed and its outlet to locate groundwater potential zones in the study area.
Intro to rainfall map in ArcGIS: download rainfall data, convert a city file to a usable format, extract a month, and apply interpolation for groundwater potential zones.
Extract rainfall data with ArcGIS multi-dimension tools, clip to your study area, and export results; decide between stacking bands, averaging years, or using a single year for groundwater potential zones.
Learn to generate an annual rainfall map by separating monthly bands from January to December, composing the bands, and summing monthly rainfall in ArcGIS to estimate 2016 rainfall.
Generate rainfall maps for the Washington, D.C. area via interpolation in ArcGIS, producing the rainfall output and preparing data for groundwater analysis and soil mapping.
If the site is down, download soil file from resources of this video.
Explore practical data management for a groundwater potential zones GIS project, organizing files, labeling with underscores, and preparing land use and overlay analyses within ArcGIS for a study area.
Explore the overlay concept in groundwater GIS, defining influence and scale to rate feature importance for land use, elevation, flood risk, and drought.
Explore how to create groundwater potential zones in ArcGIS by building a multi-criteria overlay from rainfall, slope, soil, land use, and elevation, then reclassify into five classes and map outcomes.
Use same groundwater data to map flood risk in ArcGIS by combining rainfall, soils, land use, elevation, slope, and density, and assign weights to classify high, moderate, and low risk.
This course covers everything from basic to final results. It starts from Google Search data Download and process data till last result. it also covers the use of available online data sources to prepare Groundwater. It covers all Practical aspects till final results. Only you need to have land use map ready before starting of this course. Rest of things covered in this course from basic. You no need to go anywhere outside of you room to run this project. But if you have observation data then you can generate fluctuation map also, that is optional part of this project. By using GIS it is also possible to generate groundwater maps without groundwater data also. But this data is not easily available. So, while performing groundwater potential zone analysis we not used observed data it is optional. Observed data covered in other section of this course for fluctuation map analysis. The data, which used for Groundwater analysis, same data can be used for other analysis also, like Flood risk, Drought prone area analysis. So this analysis are also performed in this course. Because data is same just difference of value. You will also learn data plotting. This project also covers watershed Delineations. If your study area is not watershed, just use study area boundary and skip watershed delineation. Therefore, it covers more than it specified. You by taking this course you not only learn groundwater, you will learn many more advanced task of GIS also, Like DEM mosaic, Data Re-Project , Cutting of study area, soil map generation etc. Therefore, This is complete project from scratch. Feel free to ask me question in Q&A Section. I assumed you know very basic of GIS to perform this analysis. This is Expert level work.
This course is in Full HD 1080p for better Experience use Setting to HD and headphones.
Only take this course if you know basic of GIS. You must have landuse landcover file before processing to this course.
