I'm trying to export a high resolution view of a map (base map only). Although it's simple to increase the resolution of the saved image, there's no way I've found to increase the level of detail. In other words, the maximum amount of detail shown on the exported image is the same as shown in the on-screen map view window. Yes, I can zoom in the map view to get the increased detail (i.e.: more roads, more labels, etc.), but then I can't print the larger area I need.
Any advice much appreciated.
What are you exporting to?
Have you tried to export a layout?
For example Export to PNG—ArcGIS Pro | Documentation allows you to specify the dpi if you export a layout.
Details of what you have to tried would help
see this guide
Introduction to exporting a map or layout—ArcGIS Pro | Documentation
There are 12 export file types available, including both vector and raster formats. The vector formats are AIX, EMF, EPS, PDF, SVG, and SVGZ, which support a mixture of vector and raster data. The raster formats are BMP, JPEG, PNG, TIFF, TGA, and GIF. They are solely raster export formats and automatically rasterize any vector data in your map or layout.
Yup, I've tried exporting a layout... same issue. I'll try to give a better description:
I have an area which I'd like to export as an image:
When I zoom in to a small area of the above, more details are shown (obviously):
When I render the first view at, say, 12000 x 14000, the level detail is like this:
The goal is to render the large area view, with a level of detail like the second zoomed-in view.
The 14000 x 12000 resolution of the exported image certainly has the pixels to support that level of detail, but there seems to be no way to actually make use of those pixels.
Ideally, I would think that ArcGIS Pro would have a way to define the exported image area separate from what is seen in the interface Map View, along with the level of detail (camera altitude?) but it appears not.
My work around, painful though it would be, is to render dozens of closeup views in a grid pattern and then stitch them all together in photoshop. 🙂
The level of map detail at a particular scale is driven by the visible scale range on each individual layer in the base map. The best solution I've found for this issue is to build my own custom basemap in ArcGIS Online. By adding each layer separately and setting the visible scale range for the layers individually, I end up with more control over the level of detail based on the overall scale of the map. We do most of our maps in 11x17 layouts, so I tailored our initial basemap for the level of detail I wanted in that size layout.
A quick but less flexible fix would be to add, for example, the building footprints layer in ArcGIS Pro on top of the basemap you selected. You can set the visible scale range on that layer so it is visible even when the basemap settings turn it off. It just gets clunky to do this for a lot of basemap layers if your projects also have a lot of non-basemap data added.
It's definitely a pain to do at the beginning, but once it's done and compiled it can be saved in ArcGIS Online as a basemap that can be used across your organization.
