Overview of AW3Dsup(TM) global 3D map service'3D Maps That You Look at' change to '3D Map That You Can Use'

Journal Articles & Books
October, 2016
Global

AW3Dsup(TM), the world's most precise global 3D map service, became the world's first five-meter-resolution 3D map covering all global land spaces in April 2016 by using Advanced Land Observing Satellite (ALOS). In addition to five-meter-resolution global map, enhanced service offers a higher-resolution 3D map at half-meter or two-meter resolution, both of which are offered on an on-demand basis using commercial high-resolution satellite imagery. This paper introduces the project history, technical characteristics, service contents, use cases and future prospects of AW3Dsup(TM).

What’s (Not) on the Map: Landscape Features from Participatory Sketch Mapping Differ from Local Categories Used in Language

Peer-reviewed publication
November, 2017
Global

Participatory mapping of local land use as the basis for planning and decision-making has become widespread around the globe. However, still relatively little is known about the conceptual underpinnings of geographic information produced through participatory mapping in given cultural and linguistic settings. In this paper, we therefore address the seemingly simple question of what is (not) represented on maps through an exploratory case study comparing land use categories participants represented on sketch maps with categories elicited through more language-focused ethnographic fieldwork.

Classifying and Mapping Periurban Areas of Rapidly Growing Medium-Sized Sub-Saharan African Cities: A Multi-Method Approach Applied to Tamale, Ghana

Peer-reviewed publication
February, 2019
Africa
Ghana

Periurban areas of growing cities in developing countries have been conceptualised as highly dynamic landscapes characterised by a mixture of socioeconomic structures, land uses and functions. While the body of conceptual literature on periurban areas has significantly increased over the past two decades, methods for operationalising these multi-dimensional concepts are rather limited. Yet, information about the location and areal extent of periurban areas is needed for integrated planning in the urban–rural interface.

The challenge of participatory mapping for agricultural investment mapping: Compromise and lessons learned for shared benefits in a project in Sierra Leone

Reports & Research
December, 2019
Sierra Leone

This document, presents a learning story from the LEGEND Challenge Fund that supported partnership projects by civil society and private sector business to test approaches through which private business can potentially contribute to more secure land rights and better land governance in agricultural investment sites and supply chains. It explains the challenges involved in a participatory mapping exercise conducted jointly by a company Natural Habitats Sierra Leone Ltd (NHSL) a member of the Netherlands based Natural Habitats Group (NHG), and the NGO Solidaridad.

Application of systematic monitoring and mapping techniques

Kenya

Drylands cover over 40% of the earth's surface and support over 2 billion people, globally (Millennium Ecosystem Assessment, 2005). In East Africa alone, over 250 million people depend on drylands for their livelihoods (De Leeuw et al., 2014) and in Kenya, 70% of the total land area is classified as arid- and semi-arid (Batjes, 2004). Over the last several decades, an increasing and more sedentary human population has resulted in more pressure on these lands, and an expansion of agricultural production into marginal dryland areas that were traditionally rangelands.

Cadastral maps as a basis for developing street maps: examples from Australia and Brunei

Conference Papers & Reports
October, 2011
Brunei Darussalam
Australia

Cadastral maps can be used as an effective initial set of data for new street maps in particular, and any type of large scale map project in general. This is due to a) a high degree of currency and accuracy of the digital cadastral database (DCDB); b) DCDB’s overall high level of reliability in terms of completeness; and c) the availability of DCDB to the public. It is within the context of these three notable features that the Australian and Bruneian experiences with DCDB are examined.

Beyond Calendars and Maps: Rethinking Time and Space for Effective Knowledge Governance in Protected Areas

Peer-reviewed publication
September, 2020
Colombia
South Africa
Southern Africa

Protected area managers rely on relevant, credible, and legitimate knowledge. However, an increase in the rate, extent, severity, and magnitude of the impacts of drivers of change (e.g., climate change, altered land use, and demand for natural resources) is affecting the response capacity of managers and their agencies. We address temporal aspects of knowledge governance by exploring time-related characteristics of information and decision-making processes in protected areas.

Retrieving the National Main Commodity Maps in Indonesia Based on High-Resolution Remotely Sensed Data Using Cloud Computing Platform

Peer-reviewed publication
September, 2020
Indonesia

Indonesia has the most favorable climates for agriculture because of its location in the tropical climatic zones. The country has several commodities to support economics growth that are driven by key export commodities—e.g., oil palm, rubber, paddy, cacao, and coffee. Thus, identifying the main commodities in Indonesia using spatially-explicit tools is essential to understand the precise productivity derived from the agricultural sectors. Many previous studies have used predictions developed using binary maps of general crop cover.

Predicted Maps for Soil Organic Matter Evaluation: The Case of Abruzzo Region (Italy)

Peer-reviewed publication

Italy

Organic matter, an important component of healthy soils, may be used as an indicator in sustainability assessments. Managing soil carbon storage can foster agricultural productivity and environmental quality, reducing the severity and costs of natural phenomena. Thus, accurately estimating the spatial variability of soil organic matter (SOM) is crucial for sustainable soil management when planning agro-environmental measures at the regional level. SOM variability is very large in Italy, and soil organic carbon (SOC) surveys considering such variability are difficult and onerous.

Quantifying the Land Use and Land Cover Changes in the Yellow River Basin while Accounting for Data Errors Based on GlobeLand30 Maps

Peer-reviewed publication
January, 2021
Norway
United States of America

Land use and land cover (LULC) change influences many issues such as the climate, ecological environment, and economy. In this study, the LULC transitions in the Yellow River Basin (YRB) were analyzed based on the GlobeLand30 land use data in 2000, 2010, and 2020. The intensity analysis method with hypothetical errors calculation was used, which could explain the deviations from uniform land changes. The strength of the evidence for the deviation was revealed even though the confusion matrixes of the LULC data at each time point for the YRB were unavailable.

Earth Observations for Humanitarian Applications

05 June 2024 - 19 June 2024

NASA’s Applied Remote Sensing Training Program (ARSET) has opened a new open, online webinar series: Earth Observations for Humanitarian Applications. Refugees, internally displaced people (IDPs), and other displaced populations are made more vulnerable to climate change impacts due to their socio-political marginalization. This three-part, intermediate training presents concrete strategies for mapping localized climate conditions with risks faced by refugee and IDP communities around the world.

The training will focus on flood risk assessments and specific challenges for assessing flood risk in refugee and IDP camps; gauging long-term heat stress in refugee camps and the challenges with decision making surrounding heat risk; and monitoring drought effects on agricultural landscapes in refugee settings using Earth observations (EO) to explore the correlations between anomalies in crop productivity and weather-based factors
