ARCGIS 10.3 ENVIRONMENT OUTPUT COORDINATE SYSTEM UPDATE

Update 3/5/19 - I have not found a way to disable the default transformation in Model Builder in Pro.

Since the data I am working with is not survey grade, I am going to stick with what is practical, which seems for the time being to disable transformations in ArcGIS Pro for NAD83-WGS84 until the industry as a whole adopts a standard. Update 12/27/18 - HAZUS confirmed that they use the IRTF00 Transformation. I would be curious to know if the same is true for data in NAD83 uploaded to ArcGIS Online, or again for the HAZUS data conversion. in ArcGIS 10.6 environment and tested for back compatibility in ArcGIS 10.3. However, when ArcMap and QGIS do not have this applied by default when using projection on-the-fly, it makes things very confusing.В Additionally, it appears that when uploading data to Mapbox in NAD83, no transformation is applied. coordinate system - EPSG Select the output coordinate system / projection. Yes it seems that the most accurate way to convert between NAD83 and WGS84 is to use the ITRF00 transformation, as ArcGIS Pro does by default. My original problem and question is more of a practical one than a technical one.

Select the Geographic Transformation NAD_1983_to_WGS_1984_5 or a more recent NAD_1983_to_WGS_1984_#ДЎ. When using the PROJECT utility, make sure to select the Geographic Transformation necessary to convert data between two geographic coordinate systems or datums. Use the Project Raster tool to project rasters into a different coordinate system permanently.Malcolm, review this Procedure to project from NAD 1983 State Plane feet to WGS 1984 Web Mercator Auxiliary Sphere (Los Angeles County, CA): You will also have more control over the parameters used when projecting.

It will be significantly more efficient to only have to project the raster one time instead of each time the operation is executed. When performing repeated operations on a raster dataset that would otherwise be projected on the fly, it is recommended that you project the raster directly before performing the analysis. The transformation method used when projecting rasters on the fly is a piecewise polynomial transformation, where the data is transformed block by block, thereby guaranteeing high accuracy.

Learn more about the output coordinate system environmentДЄutomatically transforming a raster dataset into the common coordinate system in the cases identified above is referred to as projecting on the fly.

You can set the coordinate system of all output raster datasets to be Same as Input, As Specified Below, Same as Display, or Same as Layer. To override the default behavior for coordinate systems, set the coordinate system via Environment Settings before executing the tool. The output will be in the same coordinate system as the first raster input. If the raster and feature inputs are in different coordinate systems: If the raster and feature inputs are all in the same coordinate system: The output will be in the same coordinate system as the first defined input. If more than one raster dataset is input, and they are in different coordinate systems: If more than one raster dataset is input, and all are in the same coordinate system: The output will be in that same coordinate system. Relationship of output coordinate system to input data Input type When any particular input dataset is in a different projection from that of the output, it will first be projected to that projection. The default behavior determining the coordinate system of the output is described in the following table. As a result, the coordinate system of the output will be dependent on the coordinate system of the input datasets.

If the inputs have different projections, they may be projected to temporary intermediate datasets before the selected tool operates on them. Inputs to an ArcGIS Spatial Analyst extension tool that are in the same coordinate system (same projection and datum) will be used directly.
