Tips and Tricks in ArcGIS Pro Projections and Coordinate Systems

well welcome to the third edition of tips and tricks in ArcGIS pro in this session we will be talking about projections and coordinate systems it is best practice to ensure that the data we are using in our mapping and analysis maintains the same underlying projections and coordinate systems similar to arcmap RGS pro map layouts take on the projection and coordinate system of the first layer added we can verify the spatial reference on a map by going to its properties and looking under the coordinate system properties here we will note that this map has a coordinate system WGS 1984 and has a projection applied to it which is UTM zone 16 M this can be cross-checked against our layers so if we open up the properties of our settlements layer and go to the source properties and expand the spatial reference properties we can note the coordinate system as well as any projections apply in this case we have WGS 1984 coordinate system and a web Mercator auxiliary sphere projection if we open up our roads layer and go to its properties and look at the spatial reference we'll note that this has a coordinate system of 9 1927 and has a projection of UTM zone 16 n in ArcGIS code there are two quick ways to reproject data the first is to use the project tool if we search on geoprocessing tools for a project in data the management tool box will come across and will be able to open this tool we'll select a input feature class in this case our Belize roads output feature class the output coordinate system which will be the same as our map and because our input feature class has a different coordinate system than our output coordinate system we must apply a geographic transformation for Belize we were always used in Nam 1927 to WGS 1984 number two geographic transformation Selectron and our new layer is added to the map the second method involves right-clicking our layer in the table of contents and selecting data export features this opens up the feature class the feature class tool will give our output feature class a name then like the environments tab and select the output coordinate system in this case both the the input feature class and the output coordinate system are the same just the projections are different so no Geographic transformation is needed this electron now we can check the layer properties of our newly projected layers I go into the properties and expanding the spatial reference I will do that same for the roads and we can see that our projections and our transformations have been applied I hope you enjoyed this installment of tips and tricks in ArcGIS Bo join us again next time
