Extracting spatial data from Google & OSM Maps
In today's digital age, spatial data plays a crucial role in various industries, ranging from urban planning to logistics.
Extracting data from existing map apps has become increasingly relevant due to the vast amount of valuable information stored in these applications.
Spatial data, encompassing geographic and location-based information, has become indispensable in understanding our world.
Creating spatial layers by starting spatial data collection through field data can be challenging due to resource requirements, geographic coverage limitations, data consistency, quality concerns, weather and environmental factors, data privacy and permissions, training needs, data integration complexities, and data management demands. However, overcoming these difficulties is essential as field data provides ground-truth information, validates remote sensing data, and supports various applications with careful planning, training, and effective technology usage. Fortunately, most of these spatial data have already been collected, and new data are being updated frequently.
Map apps, such as Google Maps and OSM (Open Street Maps), have become go-to resources for navigation, location search, and real-time updates. These apps contain a wealth of data that can be immensely valuable for research, business, and decision-making processes.
Extracting data from map apps offers numerous opportunities for innovation and development. It can empower businesses with location-based insights, enable city planners to optimize infrastructure, and support researchers in understanding geographic trends. Data extracted from map apps can serve as a foundation for building new applications and enhancing existing ones.
Challenges in Data Extraction: Despite the benefits, data extraction from map apps presents its fair share of challenges.
1.QuickOSM plugin in QGIS can easily be used for extract data from OSM for free.
Search and install QuickOSM plugin in Qgis
Open QuickOSM from vector manu
Here you can collect key words such as buiding, land use etc. in Layer extent or any other extent for your choice -> then simply run Query to get your desired spatial data.
2. Google Extractor gives you an oppertunity to get google data for free
Install the G Maps Extractor extention for your browser( Chrome)
After adding the extention to your browser, Searc your requiremnt then you can extract by start extracting
Here you can only download a limited number fro free, for more you need to by their service.
