![]() century to better depict the spherical surface of the earth on a flat map. Although its many advantages, this projection is not appropriate for any type of. Although it distorts areas in the polar regions, it’s become the de facto standard for web mapping of any type and is useful for large-scale (local) maps on the internet. MAPublisher is fully compatible with Adobe Illustrator CS6 and the latest Creative Cloud (2015) on both 32 bit and 64 bit systems. A satellite in an inclined orbit traces a sinusoidal wave on a Mercator map. The service contains the Australian Coastal Geomorphology Scale Guide, used to support a national coastal risk assessment. The Web Mercator projection is a variant of Mercator, Mercator Auxiliary Sphere. However, the Web Mercator uses the spherical formulas at all scales whereas large-scale Mercator maps normally use the ellipsoidal form of the projection. It uses the same formulas as the standard Mercator as used for small-scale maps. ![]() Update 3/5/19 - I have not found a way to disable the default transformation in Model Builder in Pro. The latest release of MAPublisher is available for Windows 7/8 and Intel-based Mac systems. Web Mercator is a slight variant of the Mercator projection, one used primarily in Web-based mapping programs. 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. However, when ArcMap and QGIS do not have this applied by default when using projection on-the-fly, it makes things very confusing. Additionally, it appears that when uploading data to Mapbox in NAD83, no transformation is applied. ![]() 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. > Geographic Transformation: NAD_1983_to_WGS_1984_5 With an image selected, click the Register Image button on the MAPublisher toolbar or from the menu Object > MAPublisher > Register Image.
