Coordinate Conversion

Analytics Explorer workflows that require XY locations include distance grids, well spacing, and flex gridding.

To access the Coordinate Converter, right-click in the table and select IHS Markit Analytics Explorer > Coordinate Converter.

See the following examples.

Example 1 - Adding Harmony data to the map

Harmony data is in geographic coordinates (Lat Long), but the Coordinate Converter makes it simple to add Harmony data to the map.

  1. In the table requiring conversion, right-click and select IHS Markit Analytics Explorer > Coordinate Conversion.

  2. Select the required source and target data formats, coordinate systems, and locations columns. Note that the Harmony coordinate systems are placed at the top of the list for both geographic and projected systems. When converting from geographic to projected, the matching Harmony EPSG from the source is at the top of the list. You can enter any key term in the Search box at the top of the list to narrow your search.

  1. The calculated columns are created in a new table which is then merged back to the original table based on the column(s) selected to define each unique row beside Columns to add/merge to the result table. Your selection here may be a single column that defines the row, for example UWI for well tables, but it may be multiple columns that define a single row, for example in the deviation survey table 3 columns are required to define a unique row: UWI | MD |Deviation Survey Name

  1. Click OK to begin the calculations.

Example 2 - Changing the projected coordinate reference system

My incoming data (Source) is in a different projected CRS than my current map, so I need to convert the incoming data to the map CRS (Target).

Two columns are added to the result table: X1, and Y1 assigned by UWI. These columns are the XY coordinates in the target reference system.

Example 3 - Coordinate Conversion of Deviation Survey Points

My incoming borehole deviation survey data (Source) is in a different projected CRS than my current map, so I need to convert the incoming data to the map CRS (Target).

Note that 3 columns are required to define a unique row: UWI, Deviation Survey Name, and MD
