GEOSPATIAL APPLICATION IN MAPPING MINERAL POTENTIAL ZONES

Advancements in geospatial and remote sensing technology is increasingly being adopted and used by the mining industry for exploration and identification of prospective locations. In conventional methods of field survey, geologist looks for surface manifestations that are often not perceivable through naked eye due to regional extensions. Similarly, structural features are also not identifiable in the field traverses. Remote sensing images helps to decipher these information’s on regional extents in lesser time frame. A host of earth observation satellite images like IRS LISS 3, LISS 4, ASTER, SPOT, ALOS are available providing detail information on the land resources at various resolution and sizes.

ASTER images in association with limited field inputs can be used for mapping potential anomaly regions. It is observed that using advanced images like Hyperspectral remote sensing technology can further help in delineating the different minerals. The latest in the trend is aerial hyperspectral which provides hyperspectral images at very high resolution (~3 meters), making it possible to delineate the ore bodies on the ground.

RMSI has successfully tested and has delivered niche business solution for many mining giants in various part of the world. Some notable case studies include mapping base metals in Madhya Pradesh in India, Iron in Central in India, Limestone and Chromite in Middle East and also in parts of Africa. This time tested outputs have helped the clients optimizing the field and preliminary investment cost by upto 40 per cent.

SPATIAL MIGRATION - SOLUTIONS FOR FACILITY NETWORKS

Utility service providers have made significant investments in transforming distribution networks into intelligent information using geospatial technologies for various functions viz., Planning, Design Engineering Operations, Maintenance and Customer service management. However, service providers face an inherent limitation of accurately positioning the existing facility networks to match real world entities. Currently, all traditional base geography databases are being enhanced to ensure users get benefited with precise and accurate base maps. Engineering demands spatial accuracy at least to the extent that is presently available on the hard copy or AS-built drawings maximizing operational efficiency.

Today GIS technologies fulfill the all important need to migrate and spatially position the facilities to the enhanced and accurate base map. The management of migrated facilities network can be well augmented to meet varying demands and corresponding cost-benefits for the utility operators.

This paper provides insights into effective solution adapted for migration of the existing facilities network to more precise and accurate real world coordinates with least disturbance to the business process.

GEOSPATIAL DATA TRENDS IN WIRELESS TELECOM INDUSTRY

Wireless communication has developed into one of the most emerging technologies during the last few decades. Currently, not only the availability but also the quality of the network services has become a key parameter for wireless service providers. The network design has become more crucial since the network quality is highly dependent on the distribution of the base stations. In this competitive market, efficient planning can optimize base station installations, thereby reducing the total cost of network rollout while at the same time ensuring high levels of network performance for the subscribers.

Consequently there is a need to adequately model the network environment prior to actual physical deployment of network infrastructure. To achieve this higher level of efficiency and performance, a high quality of GIS data is used as a base data for efficient network planning.

Due the growing trend in usage of high resolution imagery, data representation and retrieval has become robust for wireless industry planning, with resolutions ranging from 100m to a level of 0.3m.

TREE FALL MODELING

Hurricanes normally result in tree fall hazard. In fact tree fall hazard is one of the major concerns for building owners because sometimes the damage from tree fall outscores that of the wind. To assess the risk from tree fall, it is important to get the information on the tree coverage within the residential areas and mapping this kind of data from the conventional methods is an expensive exercise.

Through a project case study, this paper highlights an innovative yet cost effective solution to assess the loss to a given property occurring as a result of tree fall.

EARTHQUAKE DISASTER MANAGEMENT THROUGH GIS AND PROBABILISTIC RISK ASSESSMENT

REMOTE SENSING - A COMPARISON WITH SUPPLY CHAIN SOURCES

While the reliability and accuracy of remote sensing data is routinely checked through systematic sampling and ground verification, there has never been a large scale accuracy check that was commodity-based via the supply chain. In this paper the authors have made an attempt to scientifically compare remote sensing-based data with supply chain sources such as millers, exporters and wholesale commodities markets. This first-of-its-kind study was undertaken to assess the accuracy of remote sensing-based production estimations of Basmati rice for the 2005 growing season against the actual arrivals at various grain depots as well as other related sources. The survey was conducted through export, wholesale and marketing boards of Basmati in four leading rice-producing states in India: Uttar Pradesh, Uttaranchal, Punjab and Haryana.

Based on a comparative analysis between Kharif (monsoon growing season) 2005 estimates derived using remote sensing, versus the actual arrives at market, a March 2006 conclusion, based on certain calculated and logical assumptions and limitations found that the remote sensing-based estimated results for Kharif 2005 harvest provided an accuracy of 90% to 94% in the study areas. As anticipated, remote sensing based data as expressed in estimates is higher in a predictable manner than total supply chain sources, thus confirming the reliability of this project's data.

The authors consider this to be a cautious, well calculated and mathematical analyses-based study done for the first time in India. Results are re-defining certain usage of remote sensing techniques in agriculture market research and supply chain study. This study may also have an application in calibrating demand forecasting as well.

GIS FOR COMPREHENSIVE TAXATION SOLUTIONS

Special Purpose Districts (SPD's) are created by state and local agencies for the purpose of funding special items such as Library Districts, Regional Transportation Districts, Crime Control Districts, etc. SPDs play vital role in implementing sales and use tax that is collected in addition to state tax and any other local taxes.

Frequent changes in municipal boundaries due to annexations make it difficult for retailers to determine local tax jurisdictions and manage tax issues. With tax jurisdictions constantly changing and new tax jurisdiction assignment requirements mandated by state and local lawmakers, the potential liability resulting from inaccurate tax assignment poses a significant problem.

The ESRI suite offers a range of flexible functionalities, which can be used to build a comprehensive solution to ensure that the most current information is available for tax jurisdiction assessment. This paper illustrates a solution that involves in creating a nationwide SPD product and periodic product maintenance to enhance the tax application performance.
