Topographic Output

How can I get a Topographic map using MPP and MME and how accurate will it be?

Every map that gets created with Maps Made Easy gets a digital elevation model (DEM) that can be used to derive all sorts of other specific outputs. 

It is hard to quote absolute accuracy because it depends on a lot of different inputs but getting the heights within 3-4 GSD units should be achievable under ideal conditions. 

If you are referring to a contour map you can read about that here:

I followed the Maps Made Easy instructions for processing and viewing a contour map in QGIS for a 70-acre property, and the results are amazing.

The only issue I’m having is creating a high-quality output that I can share with my customer. Within QGIS, the contour lines appear to be vector-based and remain sharp no matter how far I zoom in. However, I have followed the QGIS export instructions and have not yet been able to produce a file that retains that same level of detail and clarity.

Ideally, I would like to provide the customer with a PDF or another shareable format that allows them to zoom in closely without the contour lines becoming pixelated.

Any advice you can provide on the proper export settings or recommended workflow would be greatly appreciated.

Thank you,

To export a PDF in QGIS, open the Print Layout via Project > Layouts, click the Export as PDF button on the top toolbar, and choose your save location. [1]
 
Steps to Export
  • Go to Project ► Layout Manager or Project ► New Print Layout to create or open your map composition.
  • Add your map elements, legend, and scale bar.
  • Click the Export as PDF icon (resembling a page with a PDF label) at the top-left of the layout window.
  • Select your target folder and file name, then click Save. [1, 2]
 
Export Settings & Tips
  • GeoPDF: Keep "Include Geospatial PDF features" checked if you want interactive layers and coordinates readable in compatible viewers.
  • File Size: If your PDF is too large due to background imagery, change the DPI value under the layout's side panel settings (default is often 300 dpi; lowering to 150 or 100 reduces size).
  • Vectors: Check "Always export as vectors" in the layout export panel if you need sharp lines that do not pixelate when zoomed. [1, 2, 3, 4]
