GIS and Land Information Management

Land Information Management (LIM) in GIS refers to the systematic collection, organization, storage, retrieval, and analysis of information related to land and its various attributes. It involves managing spatial and non-spatial data pertaining to land parcels, boundaries, land use, land ownership, land tenure, and other relevant information. LIM aims to provide a comprehensive and accurate representation of land-related data, allowing for effective decision-making, land administration, and sustainable land development. This can be particularly important for urban planning, environmental management, agriculture, natural resource monitoring, and other fields where understanding and managing land-related information is crucial.

Methodology

GIS can be deployed in Land Management, blending spatial and non-spatial data related to land parcels, boundaries, land use, ownership, and tenure. The purpose is clear, to provide a comprehensive and accurate representation of land-related data, fostering effective decision-making, land administration, and sustainable land development.

GIS operates as a digital cartographer, creating layers upon layers of information. The integration of geological sketches into GIS involves a meticulous process. These sketches, laden with details of geological structures, features, and information, undergo digitization. Layer information is then precisely added to attribute tables, giving birth to thematic maps that vividly portray geological features. The beauty of GIS lies in its ability to organize data, making it not just accessible but also meaningful.

Application of GIS

• Land-Use-Land-Cover (LULC) mapping – GIS facilitates comprehensive LULC mapping for effective management and monitoring programs in natural resource management, urban expansion, encroachment monitoring, and routing and logistics planning. Using high-resolution satellite imagery, diverse natural and man-made features are classified into specific LULC classes, including forests, settlements, highways, buildings, rivers, and more, tailored to project needs. The result is the delivery of land classification files in industry-standard GIS formats. LULC mapping services include digitization and classification from aerial photographs, supervised and unsupervised classification, identification, labeling, accuracy assessment, and meticulous map preparation.
• Thematic maps – Various geological features can be visually presented through thematic maps using GIS, utilizing geological sketches. These sketches encompass diverse geological structures, features, and essential geological information. Through digitization, these sketches are transformed, and layer information is added to the attribute table, culminating in the creation of informative thematic maps highlighting geological features. GIS plays a vital role in this mapping process, offering services such as heads-up digitization of geological sketches, interpretation of lithological contacts, capturing, gridding, contouring of features, as well as topographical and physiographic mapping.
• Mining/geological data management – GIS services offer legacy data assessments, data capture and quality control, ensuring integration into a coherent spatial geological database. GIS facilitates the conversion of archive data (text, maps, plates, photographs) into digital formats for efficient archiving, exploration, and analysis. Such output reports can be generated in various formats, from text summaries to composite graphical reports. For database sustainability, GIS offers well-log data capture, legacy dataset digitization, attribution creation, scanned text conversion, print image transformation, tabular information conversion, georeferencing, attribution of maps, and comprehensive data analysis and report generation.

Conclusion

As we explore the vast realm of GIS in Land Information Management, it becomes evident that this technology transcends its role as a mere tool. The insights derived from GIS applications empower decision-makers across diverse industries, fostering a harmonious balance between real-world and technology.

AABSyS actively engages in LULC mapping to support management and monitoring initiatives in natural resource management, urban expansion/encroachment monitoring, and routing and logistics planning. Additionally, our services encompass the creation of thematic maps illustrating various geological features, along with providing comprehensive geological data management services.
