Maharashtra To Start Satellite Based Land Survey & Mapping

Posted on

The state government is rolling out its massive project of satellite mapping land across 40,000 villages across Maharashtra, a move targeted to bring down land related disputes to zero in five years. The whole exercise in three phases is expected to cost Rs 1,600 crore. A detailed note to the ministry of finance also indicates that the project, which would also involve physical measurement of land, would need temporary recruitment of 25,000 people. Growing number of disputes related to revenue land records (also called 7/12 extracts) had given a fresh impetus to the project.

A pilot project had been carried out in Mulshi taluka of Pune. Once the survey is documented, individuals can source land records online. A senior revenue official said, “Chief Minister Devendra Fadnavis issued directives to accord the highest priority to bring down land related disputes in rural Maharashtra to zero in a phased manner.”

The project will be carried out as part of the National Land Records Modernisation Programme (NLRMP) rolled out across states in 2008.Revenue Minister Eknath Khadse said, “Once the survey is conducted and documented… there would be little room for any individual to challenge the documents as the survey would be meticulously carried out through satellite mapping and physical measurement.” It would cover 2,40,506 square kms and does not include Mumbai and suburbs. It does not include forest land across 61,273.62 square kms. The urban land area in the state is 5193.29 square km.

Google Introduces Project Sunroof

Posted on Updated on

Does it make sense to install solar panels on your roof? You probably have no idea. But as of today, Google knows. The colorful and recently alphabetized search monstrosity has launched a new tool called Project Sunroof. It will use data you may not have realized that Google even had to tell you how much money you can save by turning your roof into a photon harvester.

Why they are doing this?Why are we doing this?

As the price of installing solar has gotten less expensive, more homeowners are turning to it as a possible option for decreasing their energy bill. We want to make installing solar panels easy and understandable for anyone.

Project Sunroof puts Google’s expansive data in mapping and computing resources to use, helping calculate the best solar plan for you.

How it worksSelecting a single house from Google Maps.

When you enter your address, Project Sunroof looks up your home in Google Maps and combines that information with other databases to create your personalized roof analysis.

Don’t worry: Project Sunroof doesn’t give the address to anybody else unless you ask it to.

Neon Provides Airborne LiDAR Data Sample Free

Posted on

The NEON Airborne Observation Platform (AOP) is an aircraft platform carrying remote sensing instrumentation designed to achieve sub-meter to meter scale ground resolution, bridging scales from organisms and individual stands of vegetation to satellite-based remote sensing.

Since 2013, AOP has conducted a series of engineering flight campaigns at select NEON domains for the purpose of 1) testing the nominal data collection parameters for these sites; and 2) evaluating data processing techniques and obtain prototype datasets that support spatial/temporal scaling studies by the research community. The remote sensing data collected during these campaigns have been processed and several first level engineering data products are available for distribution. Since these data were collected as part of Engineering Flight Campaigns, they are considered “engineering quality” and may not have sufficient QA/QC to meet all users’ needs.

Airborne Data Types

Each AOP payload consists of a visible to shortwave infrared imaging spectrometer, a scanning small-footprint waveform LiDAR for three-dimensional canopy structure measurements, and a high resolution airborne digital camera for fine-scale land use and cover identification. AOP flight campaigns are designed to collect quantitative information on land use change and changes to ecological structure and chemistry, including the presence and effects of invasive species across landscapes 100-300km2 surrounding NEON sites.

DLR/NASA – 3D radar measurements of forest areas

Posted on

The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is developing radar technology that, for the first time, will enable a three-dimensional visual representation of forest areas from the roots to the crowns. The radar experts at DLR partnered with the US aerospace agency NASA in a measurement campaign, which has now confirmed the capability of the F-SAR system. The cooperation was aimed at validating the suitability of the radar data to infer a variety of parameters, including a forest’s height or vertical structure. A tangle of treetops and branches, through which just the occasional clear area provides glimpses of the trunks and roots growing below. Whether it is woodland with German spruces or a tropical rainforest, very few sensors are able to see through this green carpet and clearly visualise the underlying structures.

“The collaboration with NASA allowed us to really test both the sensor technology and the algorithms. We could not have hoped for better results,” said Andreas Reigber, project coordinator at the DLR Microwaves and Radar Institute.

The DLR Microwaves and Radar Institute is currently preparing for Biomass, a European Space Agency (ESA) satellite-based mission that will conduct radar observations of Earth’s surface. The main focus of the mission is to determine the volume of biomass in the tropical rain forests. In addition, the Institute is at the forefront ofTandem-L, a highly innovative satellite mission tasked with using radar to record the dynamic processes unfolding on Earth’s surface. Together, these projects promise a level of scientific insight one would not necessarily expect from flying over an area of woodland.

Remote Sensing System Releases GPM Geophysical Data Products

Posted on

Remote Sensing Systems has just released the GPM Microwave Imager (GMI) ocean product suite.

The Global Precipitation Measurement (GPM) satellite has a microwave radiometer onboard called GMI (GPM Microwave Imager).  The GPM satellite was launched on February 27th, 2014 with the GMI instrument started a few days later.  One of the primary differences between GPM and other satellites with microwave radiometers is the orbit, which is inclined 65 degrees, allowing a full sampling of all local Earth times repeated approximately every 2 weeks.

One can browse the global images or download the data files.  Please be sure to read the full description of the data products. Data are available from March 4, 2014 to the present processed as Version 8.1 data.   Products are available within 12 hours of instrument observation.

Telangana Proposes Topographical Survey of Godavari River

Posted on

Determined to utilise the allocated Godavari waters fully, the state government has decided to carry out a topographical survey of the length and breadth of the stretch of river passing through the state.

The topographical survey of Godavari will be taken up right from Sripada Yellampally project site to Dummugudem project site. The irrigation department has proposed to get the stretch of Godavari in the state surveyed for several uses like development of water resources and for scientific studies.

“We want to utilise Godavari waters fully. The survey is intended to identify where check dams could be constructed and how the water could be diverted,” engineer-in-chief C Muralidhar told Express.

The topographical studies will be carried out by using geospatial survey technology. The state government has also decided to utilise Lidar technology to conduct a study on the Pranahita-Chevella project. Lidar technology will be limited to the proposed Medigadda barrage near Kaleswaram, whereas the topographical survey will be carried out on the entire stretch of Godavari in the state, officials said.

The barrage alignment at Medigadda, the alignment of proposed canal from Medigadda to Yellampalli will be decided through the latest Lidar technology.
