In this blog post, you will explore a workflow for importing geological data maintained by a mining company in Microsoft Excel and CSV files for use in an ArcGIS Pro project.It consists of fictitious sample data, that is true to the underlying geology.Landownership information is imaginary,but reflects exploration trends around Battle Mountain, Nevada, in the early 1990s.
Excel Text File For Gis Series And TheAdditional source data was derived from the Nevada Bureau of Mines and Geology County mapping series and the US Department of Energy National Uranium Resource Evaluation (NURE) program.Values in the tables represent trace elements used in gold exploration and are indicator minerals used to assess the potential for finding viable gold deposits. Left alignment generally denotes that a column contain text strings and not numbers that may be used to determine values greater than a specific range. Right alignment identifies a column as containing numeric values. Consequently, for many worksheets, some data preparation is necessary to ensure the data is correctly identified in ArcGIS Pro. The next step will be to prepare the workbook containing rock and soil worksheets and convert and update the CSV files containing assay data before using them in ArcGIS Pro. Field names are derived from the first row in each column of the worksheet in ArcGIS Pro. If a field contains mixed data types, the content is identified as strings. Coordinates are maintained in the Easting and Northing fields and are displayed using a precision of 0.01 meters. In addition, many samples are coded by Claim Group. Recall that field names must contain only letters, numbers, and underscores. The over-limit samples in this dataset have already been resolved, so only the less than values need fixing. For example, you can add them to the map, open them in the fields view, and use them as inputs to geoprocessing tools. However, to work with Excel files in the current release of ArcGIS Pro, you must download and install the Microsoft Access Database Engine 2016 Redistributable from the Microsoft Download Center. Note the layer field names derived from the original column names in the excel table. You will use the SampleNumber field to join the laboratory assay data from the RockData table. You can confirm these locations by selecting the points and reviewing the AUPPB field values in the layer table. Before coming to Esri in 2001, he was an Esri software instructor for the Esri distributor in South Africa. ![]() ![]()
