Measure Building Height From Satellite Imagery Using ArcGIS Desktop

Image
Measure building height is not something easy to do in the field. You going to needs field equipment that is not always easy to carry around. On another occasion may be you needs Digital elevation surface data to helps you correctly measure building height. Even you going to needs finer resolution DSM that so expensive and hard to find. Is there any other way if you want to know building height in very easy way.  Lucky for you, ArcGIS Desktop has been implemented a measurement tool that is not only works in 2D space, but also in 3D space. The tool is called Mensuration Tool. It can measure point, line or polygon in 3D, so you will get Z-dimension information like height or elevation from a source data. Currently it could measure building height from high resolution satellite imagery in an intuitive way. By intuitive I means its precision of measurement will highly depends on how you do the measurement. You can directly measure house or building height using its shadow as reference, or

How to Download Active Fire Hot spot from VIIRS and MODIS using QGIS

Environmental issues hugely depends on geospatial data to help get things fixed. Geospatial data can helps in so many ways in every phases of solution formulation related to environmental and disaster issues. A lot of country have launched thousands of satellite platform to helps monitor environment condition on the earth surface. Daily data about various issues are common today. There are many of them so unique, sophisticated, and very useful to support complex analysis to overcome all those environmental and disaster management issues.  One of cool data that recently I found is daily forecast or actual information of fire Hot Spot derived from satellite imagery analysis (MODIS and VIIRS). These data can be accessed freely and easily from free-to-use Open Source GIS package Quantum GIS. By integration with QGIS, you are possible to directly made a forest fire hazard map in daily basis, and advocate the map to the related stakeholders. This is very cool because this is enabling time-ef

How to Display XY Data in ArcGIS Pro

This tutorial may be wont excite many people, but I would like to helps all the newbie learner of ArcGIS Pro. ArcGIS Pro is a monster but just like ArcGIS Desktop at its prime, we still needs a quite amount of learning time to finally grasp all the offered analysis commands and tools. So this tutorial has been made for that. Hopefully it will helps someone out there.

Geocoding Using Google Earth Pro

Image
Many geospatial and GIS experts know about geocoding. Geocoding can be defined as a automatic conversion of address to map coordinates and vice versa. From a strategic point of view, geocoding could improve the mapping process, especially if we have data that didnt have map coordinates, but it still at least have textual location information (i.e city name, country name, zip code etc). Using this location information and a geocoding processor, you can swap the address into coordinates, and finally you can get a point distribution map of your data in geographic space.  I have mentioned geocoding processor above. Now a geocoding processor is a service designed very specific way that its capabilities is only limited to conversion between addresses and coordinates. Geocoding processor could come at least in two way, it is provided by geoocoding service provider or you can make your own geocoding processor.  Currently there are many mapping companies that have provide geocoding services. Go

Route Planning Using QGIS and Online Routing API Services

Image
Route planning is one activity that may be almost everyone in this world doing in every day basis. Either plan a trip to certain tourism destination or simply looking for a route to nearest mart, it is a part of daily activities. Take Google Maps routing features as an example. It is being used by many people to plan and guide the trip activities. It is so easy to use even non GIS person can do route analysis without needed for understanding about Geography and GIS.  Plan a trip route is something, but flexibility to use the created route is another matter. You can only uses Google Maps Routing services inside a google maps apps or web. This situation is also similar with other online trip planner tools. Now what if we needs to uses the created route to another apps or devices, may be you want to put the route generated in Google Maps into your GPS handheld, so you can directly navigate your route using your own preferred device. This is also something that easily you can do. With the
