Interpolation
For more practice with Interpolation, check out our short course: Data Interpolation and Extraction
- From the Ribbon, click the Analysis tab.
- In the Geoprocessing group, click the Tools button. A new pane, Geoprocessing, will appear on the right side of the screen.
- In the Geoprocessing pane, type Natural Neighbor.
- Select Natural Neighbor (Spatial Analyst Tools).
- Under Input point features, click the drop-down menu and select HSTPoints.
- Under Z value field, choose Thickness.
- Under Output raster, change the name to HST_Interp_NN.
- Click Run.
- Above the ribbon, on the Quick Access toolbar, click the Save button.
Symbology
For more practice with Symbology, check out our short course: Introduction to ArcGIS Pro
- Right-click HST_Interp_NN and select Symbology. A new pane, Symbology, will open up on the right side of the screen. From here you can change the symbology settings, which affects how the HST_Interp_NN raster is displayed on the map. Stretched symbology displays continuous raster cell values across a gradual ramp of colors. Classified symbology displays thematic rasters by grouping cell values into classes.
- In the Symbology pane, choose Classify from the Primary symbology drop down menu. To change the number or classes, use the drop-down box under Classes. To manually alter the class intervals, double-click the upper values box you would like to edit and enter the new values. To change the color, use the drop-down options under Color Scheme.
- In the Symbology pane, choose Stretch from the Primary symbology drop down menu. To change the color, use the drop-down options under Color Scheme.
- Above the ribbon, on the Quick Access toolbar, click the Save button.
Contour
- Click Analysis> Tools > and in the Geoprocessing table, type Contour. Select Contour (Spatial Analyst Tools).
- From the Input raster drop-down menu, select HST_Interp_NN.
- Under Output polyline features, name the feature HST_Interp_NN_Contour.
- Under Contour interval type 10.
- Leave the Base contour as 0. In other projects you may want to look at the HST_Interp_NN raster range to determine from what value you would want the contour intervals to begin from.
- Leave the Z factor as 1. However, if you were using a different thickness than feet, you would want to input the foot to ____ conversion factor here.
- Click Run.
- Above the ribbon, on the Quick Access toolbar, click the Save button.
Importing Excel Data
- Open the IGOR - master list.xlsx sheet.
- Save the excel sheet to your folder, ensuring that you are saving it as a .xlsx type.
- Under the Analysis tab, click Tools and search for “Excel to Table”. Select the Excel to Table geoprocessing tool.
- For Input Excel File, select the IGOR - master list.xlsx sheet in your Playmapping folder.
- Label the Output Table as GIS_Wells
- Ensure that the Sheet section displays GIS_Wells. This ensures that the GIS_Wells sheet will be the data converted to a table in ArcGIS. Click Run.
- In the Contents tab, right click the GIS_Wells Table and click Display XY Data.
- Ensure that the X Field states longitude and the Y Field states latitude. Name the Layer GIS_Wells. For Spatial Reference, use the dropdown menu to select Current Map [Map]. The Spatial Reference should now be GCS_North_American_1927. Click Run.
- Zoom to the GIS_Wells Layer if you are unable to see the points.
- Right click GIS_Wells and click Label.
