GIS

Geographic information systems or, in short, GIS is on a rising trend in the world. Many people may think of municipal applications or route planning when GIS is mentioned. Of course, these are basic GIS applications but little pieces of the GIS world. If you check the applications you use…

Populations around the world have increasingly shifted away from rural localities to urban centers. This trend has become so persistent that more than half of the global population now lives in urban places. This shift in geography demographics has…

Building an Angular Component capable of rendering a Mapbox Web Map with GeoJSON Data as layers. In this article we are going to discuss how to create a simple Angular application with a Mapbox component that renders GeoJSON Point & Polygon data — the objective here is to learn how…

The time has come. The initial build of Navigate Maps alpha is now open to everyone. Starting today, anyone around the world can visit Navigate Maps and explore over 5,000 images! Currently showing only aerial imagery (street-level imagery is coming soon!), this early build of Navigate Maps allows users to…

Photogrammetry is the science of making accurate measurements of objects from photographs and images in general. These measurements can include the distance between objects, the size and shape of objects, and even the three-dimensional position and orientation of objects in space. Photogrammetry is used in a variety of fields, such…

The technology world (and media) is abuzz with AI, ChatGPT, and other specialized tools being released at an unprecedented rate. For many, it is overwhelming and frankly scary. We must see both the positive (embrace) and negative (avoid/counter) results of these new capabilities. This is not new. When the internet…

Although we have high-accuracy global gravity model GGMplus suitable for regional analysis, we still require better resolution for local analysis. Below I provide a way to produce super high resolution gravity from the GGMplus gravity model enhanced by spatial spectrum components from SRTM topography 30m. To start see links below…

The relationship between terrain and gravity field resembles the well-known “chicken and egg” problem. On one hand, the terrain undoubtedly affects the gravity field measured on its surface — the elevation of the terrain determines the distance to the planet’s center of mass, and the raised areas of the terrain…
