TrajectoryArcCatalogAssign coordinate system to imagesArcMapImport imagesCreate tie points to relocate images to a different pointAllows for easier viewingArcGISISISCraters are measuredScreenshots are taken to keep track of which craters have been measuredCan also be used to create a mosaic

Used for entering data and doing computationsCrater measurements are enteredAverage diameterRim heightUse ArcMap to locate coordinates of craterModeling is doneInitial conditions (pressure, gas content, etc.)Range of pyroclastsExcel
