COMPONENTS OF GIS
DATA INPUT
SPATIAL DATA MODEL
Data Model:
It describes in an abstract way how the data is represented in an information system or in DBMS
Spatial Data Model :
The models or abstractions of reality that are intended to have some similarity with selected aspects of the real world
Creation of analogue and digital spatial data sets involves seven levels of model development and abstraction
SPATIAL DATA MODEL
Conceptual model : A view of reality
Analog model : Human conceptualization leads to analogue abstraction
Spatial data models : Formalization of analogue abstractions without any conventions
Database model : How the data are recorded in the computer
Physical computational model : Particular representation of the data structures in computer memory
Data manipulation model : Accepted axioms and rules for handling the data
SPATIAL DATA MODEL
SPATIAL DATA MODEL
Objects on the earth surface are shown as continuous and discrete objects in spatial data models
Types of data models
Raster data model
vector data models
RASTER DATA MODEL
Basic Elements :
Extent
Rows
Columns
Origin
Orientation
Resolution: pixel = grain = grid cell
Ex: Bit Map Image (BMP),Joint Photographic Expert Group (JPEG), Portable Network Graphics(PNG) etc
RASTER DATA MODEL
VECTOR DATA MODEL
Basic Elements:
Location (x,y) or (x,y,z)
Explicit, i.e. pegged to a coordinate system
Different coordinate system (and precision) require different values
o e.g. UTM as integer (but large)
o Lat, long as two floating point numbers +/-
Points are used to build more complex features
Ex: Auto CAD Drawing File(DWG), Data Interchange(exchange) File(DXF), Vector Product Format (VPF) etc
VECTOR DATA MODEL
RASTER vs VECTORRaster is faster but Vector is corrector
TESSELLATIONS OF CONTINUOUS FIELDS
Triangular Irregular Network: (TIN)
TIN is a vector data structure for representing geographical information that is continuous
Digital elevation model
TIN is generally used to create Digital Elevation Model (DEM)
DIGITAL ELEVATION MODEL
DATA STRUCTURES
Data structure tells about how the data is stored
Data organization in raster data structures
Each cell is referenced directly
Each overlay Is referenced directly
Each mapping unit is referenced directly
Each overlay is separate file with general header
This document help you to prepare Triangulation Network (TIN), Hillshade Map, Slope map, interpolation and Digital Elevation Model (DEM) in a area and how to interpret them.

With EOfactory.ai, domain experts can
focus on their domain-related workflows and use automation for some of the other repeatable tasks
such as downloading imagery and
preprocessing.
The advent of technology and the vision to keep track with the latest technology, we the RKM group now indulging us in the field of GIS to integrate the mission friendly environment.
Moreover, the branch of GIS is a peculiar stream to convey the message of nature in visualizing, analyzing, interpreting the wide geographically concern scenario. A decision making tool that helps provide a better assessment and utilization of the resources.
LIDAR Magizine 2015: The Birth of 3D Mapping Artificial IntelligenceJason Creadore 🌐
Artificial intelligence (AI) has the potential to take the LiDAR
mapping market into hypergrowth. Following Moore’s law, with computation capacity doubling every 2 years, it is now possible for point cloud feature extraction to outpace the speed of data generation from laser scanning systems using artificial intelligence.

About Potato, The scientific name of the plant is Solanum tuberosum (L).Christina Parmionova
The potato is a starchy root vegetable native to the Americas that is consumed as a staple food in many parts of the world. Potatoes are tubers of the plant Solanum tuberosum, a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile
Synopsis (short abstract) In December 2023, the UN General Assembly proclaimed 30 May as the International Day of Potato.
Working with data is a challenge for many organizations. Nonprofits in particular may need to collect and analyze sensitive, incomplete, and/or biased historical data about people. In this talk, Dr. Cori Faklaris of UNC Charlotte provides an overview of current AI capabilities and weaknesses to consider when integrating current AI technologies into the data workflow. The talk is organized around three takeaways: (1) For better or sometimes worse, AI provides you with “infinite interns.” (2) Give people permission & guardrails to learn what works with these “interns” and what doesn’t. (3) Create a roadmap for adding in more AI to assist nonprofit work, along with strategies for bias mitigation.

3. SOLUTIONS FOR INDUSTRIAL ESTATES
We developed a web and mobile based “Decision Support System” (DSS) which consists all the plots,
industrial estates, roads and various other GIS layers.These layers were surveyed and mapped on GIS
platform to create a database module for the Industrial Estates Digital Support System.
Public Works Management System is created by scanning and digitizing the entire data on paper
shared by the MIDC till date and integrated with GIS platform.This produced all the details of the job
assigned, vendor’s management, maintenance contract, penalty clause and more at the click of a
button.
Data generated from existing as well as new systems would then be passed on to the GIS System,
which would
generate thematic maps to help officials and teams to take faster decisions.

6. ADVANTAGES
A holistic view for the decision makers to analyze and generate reports on the current situation and
gaps in the processes.
Align the decision to the strategy and vision for better revenue generation for the corporation.
Bringing in Agility to the complete process which will empower to reduce turn around time and increase
efficiency and productivity.
Visually enhancing user experience for better understanding and data visualization.
14. IDENTIFICATION OF POSSIBLE UNAUTHORIZED CONSTRUCTION
(UC) - USING TEMPORAL ANALYSIS
Identification of Possible UC:
Unauthorized Construction of Building
Add. Floors Unauthorized Construction
Encroachments Checking (using rule
engine)
Illegal Acquisition of land
25. IMPACTS BY DSS (BASED ON FEEDBACK FROM CLIENT - GIDC)
All departments were able to visualize the attribute data on a GIS map which Resulted in faster Decision
Making.
Productivity of on ground officers increased by 30% due to presence of DSS.
Revenue model was impacted in a very positive manner and increased by 20% in a year.
With its enhanced degree of efficiency and transparency, the system would be a landmark for
industrial estates across the country.
Temporal analysis leads to better utilization of land use and quashing illegal activities.
