Tools for fixing geometry of shapefiles
Geographic Information SystemsHow do I fix geometry in Arcgis? To resolve this problem, run the Recalculate Feature Class Extent tool on the dataset. Enterprise geodatabases automatically check and repair feature geometries when the features are uploaded to the database, so using the Check Geometry and Repair Geometry tools with enterprise feature classes is unnecessary. How do you

Geometric difference between equal-area and conformal projection
Geographic Information SystemsConformal projections preserve angles locally, so the shapes of features appear true. But the cost of this quality is the distortion of areas and distances. Equal area projections preserve area, at the expense of angles, so the shapes of some places appear skewed. What is the difference between equal area projection and conformal projection? For
