Self-portrait of a city. City and Architecture in Bologna in the maps between the 18th and 19th centuries

Disegnare con, 2012
The plan, being project tool and representation at the same time, allows an understanding, by means of ancient cartography, of the ancient city as an entity with its own identity connotation, whose definition derives mainly from the clarity of the ...

Using Fine Sediment Monitoring to Quantify Sand Loading Over Time

River Research and Applications, EarlyView.
ABSTRACT Riverine sand loading can lead to geomorphic change, impacting river processes like lateral migration and vertical aggradation or degradation. Yet many sediment monitoring programs track only fine sediment measurable as total suspended solids (TSS). Here, we assess the ability for TSS data to be used to determine sand loading.

DETECÇÃO, RECONHECIMENTO E GEORREFERENCIAMENTO DE LOGOTIPOS

Colloquium Exactarum, 2013
Mobile Mapping Systems (MMS) Land collect data for mapping routes and provide data for geographic information systems. They integrate digital imaging sensors, navigation and positioning embedded, thus they collect data for mapping streets and avenues

Use of Mercator cartographic representation for Landsat 8 imageries

Geodesy and Cartography, 2017
Nowadays Marine Geographical Information Systems (MGIS) play an essential role in several research activities, the most part of them related to solve Geoscience problems. The nautical maps, containing most of the information used by the marine navigators,

Georeferenced data in epidemiologic research [PDF]

Ciência & Saúde Coletiva, 2008
This paper reviews some conceptual and practical issues regarding the application of georeferenced data in epidemiologic research. Starting with the disease mapping tradition of geographical medicine, topics such as types of georeferenced data, implications for data analysis, spatial autocorrelation and main analytical approaches are heuristically ...

Using time‐series remote sensing to identify and track individual bird nests at large scales

Remote Sensing in Ecology and Conservation, EarlyView.
Time‐series airborne imagery can potentially track individuals over time to collect information beyond one‐off counts. Using weekly UAS‐based imagery of wading bird colonies, we develop an automated approach to identifying nests. Our algorithmic approach detected 68–74% of known nests and exhibited similar performance to human review of imagery ...

Release the HOGS: An unsupervised marker extraction, classification and georeferencing approach for biodiversity data

Methods in Ecology and Evolution
Distributional data are essential for understanding species and community responses to environmental and anthropogenic change. Large biodiversity databases provide key information on distributional patterns, but their temporal coverage can be limited ...

A georeferenced river quality model

Water Science and Technology, 2001
Water quality models have reached a high degree of sophistication, but their weak side remains user interface and output georeferencing. The aim of this paper is to propose an interfacing procedure between two widespread but specialised programming environments: ArcVIEW as a Geographical Information System (GIS) and Matlab as a scientific programming ...
