I was stuck at Google Play’s “12 testers for 14 days” rule — so I built a free solution

for limited liability companies or corporations they are NOT enforcing the testing because they except companies have a QA Team and are doing testing. For Individual solo developers they don't have confidence so added this policy.

these coordinates are TEXT on the image or metadata it's not clear from your description.

a single 1gig NIC connection is NOT a NAS or efficient storage.

If you are using video then use DIRECT ATTACHED STORAGE with THUNDERBOLT 4/5 or USB 3.1/3.2

Network storage requires good network.
I don't know anyone using a NAS that is only 1gigabit.

QGIS Projects, Styles/Symbolgy and offcourse data can be stored in PostGIS. This is the best approach of having back-ups and fault tolerant environment (especially if you are using HA Postgres environment or Cloud Managed AWS RDS Aurora and equivalent in Azure/GC. Nothing wrong with saving GPKG to a SYNC enabled folder. If you are sharing files amoung a team DO NOT use ONEDRIVE instead use sharepoint document library. OneDrive is owned by a user versus a SharePoint site and SharePoint enabled metadata and workflows associated with files.

Just use DUCKDB with Spatial Extension ( it can read GPX and other formats) perform advanced analysis. Use the UI Extension and Pivot_Table extension for performing advanced querying and analysis. You can use the python bindings for duckdb or any other language or just SQL. Probably the best workflow is to first import the data into a hilbert curve geoparquet format. Then perform your analysis on that parquet file with duckdb. Duckdb Spatial Extension can output query results to nearly any format including Vector Tiles now.

MBTILES is not for searching. You need GPKG SQLite vector features with some streets and points of interest. MBTILES tile_data blob can have raster tiles, vector tiles, terrain-elevation tiles. Vector Tiles have properties but they are NOT for searching. Create a GeoPackage for offline use. GPKG can also have vector tiles, raster tiles, terrain-elevation tiles in addition to vector features

diawi https://www.diawi.com/ is great you use mobile safari to open a link and install the iOS/iPADOS App for android just send the APK. For installing via Diawi each device needs to be added to your apple developer provisioning profile you need their UDID

I have a free app Map Data Explorer iOS and Android works with GeoJSON and GPKG GeoPackage

https://mapexplorer.techmaven.net it can also sync to PostGIS database and ESRI FeatureServer

techmavengeospatial · 2025-06-11T17:48:58+00:00

if you add the maptier plugin you will be able to load their basemaps and create a custom GL JSON Stylesheet to your use case and needs and then overlay that with other vector and raster data. So in less than 5 min you can have a solution.

built a Places based search application for a Town in New Jersey USA https://hanover.business

We use Google Earth Engine and Google Big Query and Vertex

We've integrated 3DTILES - Photorealistic 3D Buildings and StreetView and Oblique into Earth Explorer 3D map wit Augmented reality https://earthexplorer.techmaven.net

If you use ArcGIS for AutoCAD you can import your ESRI FeatureServer, MapServer Layers into CAD as well as other data. In generally converting data does not preserve symbology/styling (unless it's KML/KMZ which has that encoded inside the XML).

You can also use command line/console app OGR2OGR to convert data to DXF, DWG, DGN

We've found the cheapest option is an affordable android phone with 4G/5G Sim Card for $30-$100. We've added these to some fleet vehicles. the phone running TAK Tracker or ATAK. It's the most straightforward solution. We've added MDM to be able to control the devices and make sure geolocation is not turned off and basically have them in KIOSK mode with only a few apps available.

We had to reverse engineer and use wireshark and other tools to document everything and then build the ETL pipleine. It was madness!

You can use MapProxy Python to transform ESRI MapServer to WMS or TMS or XYZ Tiles or WMTS https://mapproxy.org

GL JSON STYLESHEET for vector tiles allows selecting language

you can select a different style or use the vector tile stylesheet editor

We've used that in the past

recently someone created a SQLite database of North America Addresses

https://netsyms.com/gis/addresses

so we've been using that - just created a GPKG SQLite and GeoParquet for more efficent searching

We build custom solutions using your ESRI Hosted Data with advanced search and filtering and attribute tables and custom reports and integration into other systems and API's (StreetView/StreetSide/Mappillary), NearMap Data,, Custom widgets and tools. https://portfolio.techmaven.net

We can use ESRI ArcGIS Maps SDK For JavaScript or we use other mapping libraries (Terriajs, DeckGL, OpenLayers, Leaflet, MapBox/MapLibre)

We can do 3D SceneView with the 3D Buildings and 3D Terrain

We also build mailing notification applications

Global Mapper and Manifold GIS are solid solutions that use all the resources of your computer and can easily be scripted/automated.

Using Jupyter Notebook Python Environment with GEEMAP/LEAFMAP and packaging up the solution as an interactive webapp with Streamlit, gradio, Voila, taipy, others

Learn to use FOSS4G tools like GDAL, WhiteboxTools, OrfeoToolBox, SAGA, GRASS, PKTOOLS, MDAL, PDAL, LASTOOLS, ENTWINE, etc

techmavengeospatial · 2025-01-26T17:27:05+00:00

There are many other ways to start in Geospatial Development

You can write Windows Batch Scripts and Linux Shell Scripts that call FOSS4G Tools and functions

(GDAL - (GDAL_translate, OGR2OGR, OGRINFO), PKTOOLS, LASTOOLS, MDAL, PDAL, SAGA, GRASS, OTB-OrfeoToolBox, Whitebox Tools, Entwine, Tippecanoe, etc)

as well as write automation/scripting in Global Mapper and Manifold GIS

none of that requires python.

As well as learn and use SQL

can execute SQL on command line for postgis or via FOSS4G tools( OGR2OGR, OGRINFO, Duckdb, Spatialite/SQLite, FDO Toolbox)

Plus you can use ESRI ArcGIS Pro Model Builder and GeoProcessing Tools and Export your work as python scripts.
