1.0 Introduction1.1 BACKGROUND Advent of WWW or Internet and GIS technologies = Web
GIS or Internet GIS
The geospatial industry is gradually moving away from the traditional workflow in which teams of analysts use expensive desktop software to produce geospatial products (Joel, 2013).
Many software solutions are adopting cloud based GIS
Examples:Commercial and Proprietary = ESRI ArcGIS onlineNon-commercial and Open source = QGIS Cloud
1.0 Introduction (cont.)1.1 BACKGROUND (cont.) Sample Web Map or GIS: QGIS Cloud

1.0 Introduction (cont.)
1.2 PURPOSE
To evaluate the functionality, usability and accuracy of open sources web and desktop based python geospatial libraries or API
To gather knowledge about python geo-processing ability in web GIS and geospatial analysis
1.0 Introduction (cont.)
1.2 PURPOSE (cont.)
To design, develop, deploy, test and deliver a prototype geospatial web map application using effective open source solution and standards.
To explains how web-based mapping works, common functionality provided, and evaluates the functionality provided by map service providers as well as the offered usability
1.0 Introduction (cont.)
1.3 PROBLEM STATEMENT
Having some competence in programming, application development and software management has become a critical requirement for many geospatial professionals
In this region of the world (Nigeria), little or no attention is given to it by modern surveyors (Geomaticians)
1.0 Introduction (cont.)
1.4 AIM AND OBJECTIVES
The aim of this dissertation will be to:
Evaluate the potentials of python geo-processing algorithms specifically in the development of web-based mapping and for conducting geospatial analysis.
1.0 Introduction (cont.)1.4 AIM AND OBJECTIVES (cont.)There are three objectives identified for this dissertation to achieve the stated aim:
a) Design and implement a prototype interactive GIS maps for the web which provide basic interactive web browser tools such as: zooming, panning, and layering of themes
b) Automate a specific, repetitive geospatial analysis task with minimal overhead.
c) Create a geospatial program that's easy to share, and have complete control of the underlying algorithms, data, and execution.
1.0 Introduction (cont.)
1.5 STUDY AREA DATASET
The dataset to be exploited in the research will be administrative boundary map of Nigeria.
The main geographical coordinate of Nigeria isLatitude: 10º 00’ North of the Equator andLongitude: 8º 00’ East of Greenwich Meridian.

1.0 Introduction (cont.)
1.6 METHODS
First phase, an evaluation of traditional and modern web mapping application technologies as well as the most popular technologies associated with python API will be performed
An analysis of the collected literature will then be made to filter out the relevant technologies for increasing the user experience and interactivity of modern web mapping applications and geo-processing analysis.
1.0 Introduction (cont.)
1.6 METHODS (cont.)
Finally, a web-based application prototype will be developed and implemented by using the technologies selected on basis of the comparative study.
Conclusions about the eligibility of the selected technologies and future development potential will then be made.
1.0 Introduction (cont.)
1.7 STRUCTURE OF DISSERTATION
This research will be comprised of three phases:
Phase 1: Evaluation and problem definition
Phase 2: Prototype system design and implementation
Phase 3: Prototype system enhancements and advanced query implementation.
