Method for Automated Georeferencing and Integrating Printed Maps in GIS for Collecting Addresses

Abstract

<p align="justify"> Addresses are important data for urban applications. About 80% of the information local authorities use have a geographic component that is generally related to addresses. Addressing systems efficiency depend on the quality of addresses locators. There are several methods to collect data. Surveys from the field are essential: GPS and pre-printed maps can be used to achieve this goal. GPS surveys from the field may be a solution, but it remains practical only for limited areas. To insure an accepted accuracy, GPS methods need special considerations that are time and money consuming. For Casablanca’s addressing locators, an alternative approach was adopted to collect 400 000 points. It took two months, 200 operators and 3500 printed maps to cover a study area of1,226 km². This paper is to develop an optimized approach based on automated procedure for reintegrating printed maps in a geographic information system (GIS). It saves georeferencing time from 5min to just seconds per document. It insures, more importantly, an accuracy that is between20 cmto1 mfor scales that are between 1/500 and 1/2500. It ensures maps’ integration, independently of base map and coordinates system by introducing the notion of Georeferencing Code (GC). </p

Detalhamento dos processamentos (georreferenciamento, classificação supervisionada, não supervisionada e fusão) em imagens geradas pelos sensores de diferentes satélites para o município de Santa Rosa-RS

“…O processo de georreferenciamento das imagens objetiva eliminar o erro de posicionamento remanescente, que é a diferença entre as coordenadas reais (existentes no terreno) e aquelas presentes na imagem (EL IMAME MALAAININE et al, 2013). Sendo esta etapa final do processamento de correção das distorções geométricas da imagem e deve ser executada pelo usuário (SARAIVA; MITISHITA; CENTENO, 2012).…”

OMT-G Modeling and Cloud Implementation of a Reference Database of Addressing in Morocco

“…[13] Morocco is composed of 16 regions. The most important region is the region of Casablanca, with more than 3.6 million habitants [7]; the administrative capital is Rabat.…”

“…In Morocco, some researches took an interest in urban phenomena such as detecting slums [4], urban heat islands [5] and regional urban applications [6]. We present in previous works [7][8][9] a method for collecting addressing locators from the field, but an effort of modelling and standardization is needed to establish a common ground for addressing activities in the scale of our country.…”
