One SQLite container, two different maps: how MVT tiles differ from PNG tiles in size, styling, labels, Retina support and the clients that open them.
Inside the HTML map: Leaflet from a CDN, GeoJSON data inline, a layer switcher and attribute popups. What it needs to open and where its limits are.
Inside the elevation GeoTIFF: one Float32 band in metres, declared NoData, compression, your chosen CRS and honest warnings about coarse grids and voids.
Inside QGIS project files: the XML of QGS, the ZIP with QGD in QGZ, relative layer paths, styles, layouts and a project built from a GeoPackage.
Inside DWF 6: the version prefix, the ZIP package, the W2D stream, an A3 sheet and layers. How our map file is built, where to open it, how it differs from DWG.
How to move an export onto your own CAD layer standard in one pass: list the layers, write a mapping table, run the layer translator and prove nothing was lost.
Three working routes from OpenStreetMap to AutoCAD: a ready DWG from the map builder, import through AutoCAD Map 3D and Civil 3D, QGIS and ogr2ogr. Plus KML and KMZ to DWG, a comparison table and FAQ.
Three basemap services by the numbers measured on 2026-09-21: formats, area caps, pricing, what a guest can see. The working path to DWG, OBJ and COLLADA, plus a 'What we don't have' section.
How to get an OpenStreetMap map into Adobe Illustrator as real vectors: which format to download, how to open it, and what to do with layers, strokes, fonts and print prep.
How to turn real-world terrain anywhere into an STL and print it: vertical exaggeration, millimetre scale, a watertight base, and splitting a large area into printable tiles.
How to download a city's tiles as one file and open it: MBTiles is an SQLite container for offline use and Android (OsmAnd, Locus Map), PMTiles is one file for the web without a server.
A Saint Petersburg map in DWG: why the whole city makes a heavy file, how to limit the area, which layers to take, whether to pick the ~MSK-78 zone or UTM 36N, and how to open the file.
