Background: Spatial epidemiology is used to evaluate geographical variations and disparities in health outcomes; however, constructing geographic statistical models requires a labor-intensive process that limits the overall utility. We developed an open-source software for spatial epidemiological analysis and demonstrated its applicability and quality. Methods: Based on standardized geocode and observational health data, the Application of Epidemiological Geographic Information System (AEGIS) provides two spatial analysis methods: disease mapping and detecting clustered medical conditions and outcomes. The AEGIS assesses the geographical distribution of incidences and health outcomes in Korea and the United States, specifically incidence of cancers and their mortality rates, endemic malarial areas, and heart diseases (only the United States). Results: The AEGIS-generated spatial distribution of incident cancer in Korea was consistent with previous reports. The incidence of liver cancer in women with the highest Moran’s I (0.44; p < 0.001) was 17.4 (10.3–26.9). The malarial endemic cluster was identified in Paju-si, Korea (p < 0.001). When the AEGIS was applied to the database of the United States, a heart disease cluster was appropriately identified (p < 0.001). Conclusions: As an open-source, cross-country, spatial analytics solution, AEGIS may globally assess the differences in geographical distribution of health outcomes through the use of standardized geocode and observational health databases.

QGIS is a free and open-source software that allows viewing, editing, and analyzing georeferenced data. It is a Geographic Information System (GIS) software composed by tools that allow to manipulate geographic information and consequently to create maps which help to get a better understanding and organization of geospatial data. Unfortunately, maps created directly in the GIS desktop software are not automatically transferred to a website. This research aimed to compare publishing capabilities in different QGIS plugins to create Web Maps. This study analyzes four QGIS plugins (QGIS2Web, QGIS Cloud, GIS Cloud Publisher and Mappia Publisher), performing a comparison between them, considering their advantages and disadvantages, the free and subscription plans, the tools offered by each plugin and other generic aspects. The four plugins were tested in a specific case study to automatically obtain different Web Maps. This study could help users to choose the most adequate tools to publish Web Maps under QGIS software.

This work assesses sea-level rise using three different models created on Free and Open-Source Software for Geographic Information System (FOSS4GIS). Based on regional projections of Special Report on Climate Change and Oceans and Cryosphere (SROCC) of the Intergovernmental Panel on Climate Change (IPCC), the models were applied to a case of study on Rio Grande do Sul coast &ndash; Brazil under different sea-level rise scenarios by the end of this century. The End Point Rate for QGIS (EPR4Q), calculates a shoreline projection using End Point Rate method. The Uncertainty Bathtub Model (uBTM), analyses the sea-level rise impact by the uncertainty of sea-level projec-tions and vertical error of the Digital Elevation/Terrain Model (DEM/DTM). The Bruun Rule for Google Earth Engine Model (BRGM) predicts the shoreline position with sea-level rise, using topographic and bathymetric data from Unmanned Aerial Vehicles (UAV) and Coastal Modelling System (SMC &ndash; Brazil), respectively. The results indicated a maximum shoreline retreat for 2100 of -502 m and -1727 m using EPR4Q and BRGM, correspondingly. The uBTM using the land-use of Mapbiomas showed a maximum of 44.57 km2 of urban area impacted by the sea-level flood. This research highlights the possibility of performing coastal management analysis in GIS environ-ment using non-commercial software.

Seiring meningkatnya mobilitas masyarakat dan tingginya kebutuhan informasi berupa peta, Geographic Information System (GIS) bukan hanya sekadar tren teknologi, tetapi telah menjadi sebuah kebutuhan. Ketatnya persaingan para vendor perangkat bergerak (mobile device) dengan berbagai fitur dan keunggulan, secara tidak langsung berdampak positif bagi konsumen teknologi  mobile salah satunya operating system (OS) Android. Dengan adanya operating system (OS) Android yang memberikan banyak keuntungan salah satunya adalah OS Android yang bersifat open source, para pengembang aplikasi Android dapat membuat sebuah aplikasi sesuai kebutuhan termasuk pembuatan aplikasi Peta ATM. Disamping itu pada handphone Android juga telah tersedia GPS sebagai penetuan posisi pengguna. Peta ATM dengan menggunakan aplikasi GPS merupakan sebuah aplikasi yang dapat digunakan oleh banyak kalangan. Banyak manfaat yang dapat dirasakan dengan menggunakan aplikasi ini, diantaranya adalah dengan mengetahui sebuah lokasi dimana posisi user berada. Begitu juga dengan aplikasi peta Automatic Teller Machine (ATM) dapat memberikan kemudahan bagi para pengguna handphone berbasis operating system Android untuk mengetahui dimana letak posisi ATM BNI yang berada di wilayah Purwokerto dan sekitarnya. Dengan adanya aplikasi peta ATM BNI diharapkan para pengguna yang belum mengetahui secara lengkap kota Purwokerto dapat dengan mudah dalam mencari lokasi ATM.
