The document discusses the key components and concepts of a National Spatial Data Infrastructure (NSDI). An NSDI aims to integrate distributed geospatial data through partnerships between different levels of government and private organizations. It establishes standards, frameworks and metadata to facilitate discovery and sharing of geospatial data. Central to an NSDI is a clearinghouse that allows users to search metadata from distributed servers according to common protocols. When properly implemented through the coordination of stakeholders, an NSDI can help reduce data duplication, lower costs and make critical spatial information more accessible.
Gis applications in tourism a tool for sustainable tourismpankaj kumar
GIS can be an effective tool for sustainable tourism development by helping decision makers evaluate environmental impacts, identify potential conflicts, and model relationships between tourism and other sectors. GIS allows tourism data to be integrated and analyzed spatially, helping with resource mapping, impact assessment, and tourism planning. Some benefits of GIS for tourism include cost savings through efficiency, improved decision making considering location factors, better communication of geographic information, and managing tourism development geographically. While challenges remain, GIS has been successfully used in tourism applications like mapping attractions and building interactive online maps.
This document introduces GIS (geographic information systems) and provides examples of jobs and professions that utilize GIS. It states that GIS allows users to display, analyze, and interact with geospatial data on maps. The bulk of the document lists over 100 examples of careers that use GIS, ranging from academic research and advertising to wildlife management, disaster response, and transportation planning.
This document provides an introduction to Geographic Information Systems (GIS). It defines GIS as a computer system for capturing, storing, manipulating, analyzing and presenting spatially-referenced data. The document discusses examples of GIS applications, the history of GIS from the 1970s to present, and its use in fields like urban planning, hydrological modeling and the water sector. It also compares open source GIS software like QGIS to proprietary software like ESRI ArcGIS, and reviews some key open source GIS tools including GDAL, Python and OSGeo4W.

GIS and Remote Sensing to study urban-rural transformation during a fifty-yea...Maurizio Pollino
C. R. Fichera, G. Modica, M. Pollino (2011).
Presented at "Computational Science and Its Applications - ICCSA 2011 International Conference", Santander, Spain, June 20-23, 2011.
A relevant issue in Remote Sensing (RS) and GIS is related to the analysis and the characterization of Land Use Land Cover (LULC) changes, very useful for a wide range of environmental applications and to efficiently undertake landscape planning and management policies. The methodology described has been applied to a case-study conducted in the area of the Province of Avellino (Southern Italy). Firstly, aerial photos and Landsat imagery have been classified to produce LULC maps for a fifty-year period (1954÷2004). Then, through a GIS approach, change detection and spatiotemporal analysis has been integrated to characterize LULC dynamics, focusing on the urban-rural gradient. This study has shown that LULC patterns and their changes are linked to both natural and social processes whose driving role has been clearly demonstrated: after the disastrous Irpinia earthquake (1980), local specific zoning laws and urban plans have significantly addressed landscape changes.
This document provides an overview of geography awareness week and GIS. It discusses what GIS is, including how it can be used as a geodatabase, for geovisualization, and spatial analysis. It then discusses several applications of GIS in areas such as natural resource management, emergency response, social science, history, and trends in online GIS, cloud/mobile GIS, 3D-GIS, and volunteered geographic information.
This document provides an overview of map design using GIS software. It discusses important elements to include in maps such as titles, legends, scale bars, and north arrows. It also covers choosing appropriate symbology for different map features, file formats, and resolutions for different map outputs. The document is intended to teach learners how to design effective maps using GIS software.

Understanding Coordinate Systems and Projections for ArcGISJohn Schaeffer
Everything you need to know to work with coordinate systems and projecting data in ArcGIS. The presentation starts by explaining the terminology, and then discusses the details you need to know to actually work successfully with coordinate systems, use the proper projections, and geographic transformations. This is a very practical look at a complex subject.
This document provides a short introduction to Geographic Information Systems (GIS). It discusses the purposes of GIS, including using GIS to understand phenomena that have both geographic and temporal dimensions. It also describes how GIS allows users to enter, analyze, and present georeferenced data. The document outlines how GIS represents real world features through models like maps and databases and discusses spatial databases specifically. It positions GIS as existing at the intersection of geography and information science and technology.
Pengantar Structure from Motion PhotogrammetryDany Laksono
Structure from Motion (SfM) photogrammetry can be used to extract 3D point cloud data and generate digital elevation models (DEMs) from optical camera sensors. The SfM process involves feature detection, feature matching between images, sparse reconstruction to estimate camera positions and an initial 3D geometry, dense reconstruction using multi-view stereo to generate depth maps and a dense point cloud, and texturing to create 3D models. The resulting products include sparse and dense point clouds, DEMs, and textured 3D models. While powerful, SfM has limitations for scenes with featureless surfaces, repetitive patterns, or thin structures. Open-source SfM software includes WebODM, OpenMVG,

Introduction to MAPS,Coordinate System and Projection SystemNAXA-Developers
This document discusses key concepts in GIS including maps, coordinate systems, map projections, and their application in Nepal. It defines analog and digital maps, and explains that the earth is an ellipsoid rather than a perfect sphere. It introduces geographic and rectangular coordinate systems, and defines map projections as methods to represent the curved earth on a flat surface. The document outlines the Everest ellipsoid and UTM/MUTM projection systems used in Nepal.
This document discusses leveraging geography with information and communication technologies (ICT). It summarizes that geography is critical to information infrastructure, society, and the economy. It then discusses why ICT is needed in geography due to the large volume and graphical nature of geographical data, and how ICT has automated geoprocessing tasks over the decades. Finally, it outlines research areas in geography and an educational and research agenda to further develop the field.

1:25 000 - 1cm uz kartes atbilst 250 m dabā
1:50 000 - 1cm uz kartes atbilst 500 m dabā
4
5. Kā izmantot grafisko skalu
• Nepieciešams precīzs lineāls.
• Mērīšana būs vieglāka un precīzāka, ja izmantosiet adatu cirkuli.
5
6. Kā aprēķināt attālumu pēc mēroga
• Mērogs 1:50 000 nozīmē, ka viena attāluma vienība uz kartes līdzinās
tādām pat 50000 vienībām apvidū.
• 1 cm uz kartes ir 50000 cm apvidū
• 50000 cm = 500 m
• Atmetam pēdējās 2 nulles un iegūstam cik metri ir dabā.
6
7. Piemērs aprēķinam
• Karte: 1:50 000
• 1 mm uz kartes = 50 m dabā.
• Attālums uz kartes ir 23 mm.
• Lai uzzināt attālumu dabā – Xm, var izmantot šādu formulu:

kartē?
Atbilde: 1000 m dabā jeb 1 km.
Atbilde: Kartes mērogs ir 1:25 000. Cik lielam attālumam dabā atbilst 4

15. Apvidus raksturojums pēc kartes
Lai mēs varētu raksturot apvidu uz kartes ir nepieciešams zināt
topogrāfiskos apzīmējumus.
Jo vairāk apzīmējumus mēs spējam atpazīt, jo pilnvērtīgāk spēsim
raksturot apvidu.
Karte mums sniedz ļoti daudz informācijas par apvidu, tādēļ svarīgi visu
informāciju ir sakārtot pa plauktiņiem, samazinot iespējamību
nepamanīt svarīgas detaļas.
15
16. Apvidus raksturojumā nepieciešams
iekļaut informāciju par:
Reljefu - par būtiskām izmaiņām uz zemes virsmas.
Hidrogrāfiju - par apvidū sastopamiem ūdeņiem.
Augu valsti - par mežiem, purviem utt.
Satiksmes tīklu - par ceļiem, dzelzceļiem.
Apbūvi - par nozīmīgām ēkām, dievnamiem, utt.
Apdzīvotību – pilsētās, ciemos – blīvi, ārpus – reti.

Augu valsts: Blīvs mežs, pļavas, neliels izcirtums un
jaunaudze (ja neesi drošs par apzīmējumiem,
meklē tos kartes apakšējā daļā).
Satiksmes tīkls: Apvidus ZR daļā iebraukts ceļš.
Apbūve: Nav.
