Over the last couple of years, we have seen an increase in demand and offerings of geospatial solutions in the cloud for tasks like web map creation, centralized data storage and management, data vizualization and so on. There is a lot of Software-as-a-service (SaaS) options to explore, but in this article I want to briefly discuss if SaaS is the right thing for you, or wether you should look into rolling your own.
I was reading an article entitled “China, the megalopolis of 110 million inhabitants that impresses the world” on a popular online journal (see article) and after a dozen lines read: “Beijing is already surrounded by six ring roads, [… ] but the seventh will be 940 kilometers long.” How many are 940 km for example along a circle, as the Circular Highway of Milan?
In a statistical report entitled US Smartphone Use in 2015, it revealed that some 88 percent of American smartphone owners use their handset as a map or navigation device. There are various ways on how you can utilize your handset as a GPS device, either through its built-in map features or via other downloadable applications. If you are one of those planning to maximize their smartphone as a GPS locator, here are the pros and cons of using your handset as a digital geographical tool.
Most of you guys are aware of one or two GIS systems. But what about the functionalities of others? How can you compare these? @Dragons8mycat has done some great work in providing a way to huge excel sheet where he compares nearly all of the available GIS systems.
Due to my work with a multitude of statistical packages in my career I may be able to evaluate a lot of them. I’ve first used Excel for my calculations as most of the normal users do. I like the idea behind a spreadsheet and the combination of data and click-to-do functions. Nevertheless I’ve often managed to gain control again over my spreadsheets as they’ve evolved to some unintelligible things on my hard drive. The ruler of this evolution was spreadsheet “data_results_0.9.1a_final_b_ws.xls”…
In my recent articles I was writing some hints and tutorials for creating a webmap. So what is the basic concept behind it and what are the possibilities. 1. Hail the GMAP creator GoogleMaps was probably the main step in webmap perception and usage. Until now it is the quasi standard application for viewing spatial content. The ongoing developments in the keyhole markup language increases the possibilities and usability in everyday work including geocoding and usage of raster as layers:
In one of my last seminars relating remote sensing techniques I was blamed for calculationg the NDVI and SAVI directly with the ModelMaker in Erdas Imagine using digital numbers (so-called DNs) instead of reflectance values. So I analyzed the influence of using DNs instead of reflectances. You can see some little thoughts and results on that here…
