  2. NDVI images with Sentinel 2

    Thank you for your answers. I have carried out some tests with 1C and 2A images of the same day and 2A values are usually higher due to the reflectance correction. I wonder to know if the time of the day when the image is taken (or in other words: the amount of light or the height of the Sun) affects to the real values of the NDVI.

  9. Event: Use of GIS and Remote Sensing in Disaster Risk Management Course Venue: Indepth Research Services, Nairobi, Kenya. Event Date: 11th – 15th June 2018. NITA CERTIFIED RECENT CLIENTS INTRODUCTION Disaster risk information is spatial in nature and Geographic Information Systems (GIS) play an important role in disaster risk management. Rapid population growth and urbanization combined with extreme climatic events are causing a rapid increase in vulnerability of communities exposed to hazardous events. Natural disasters inflict severe damage on almost the entire spectrum of social and natural habitats, ranging from housing and shelter, water, food, health, sanitation, and waste management to information and communication networks, supply of power and energy, and transportation infrastructure. There is a great need to utilize disaster risk information in planning for effective coping mechanisms of disaster risk reduction. For this, there is a significant need to create awareness among the disaster management professionals regarding the importance of GIS and Remote Sensing. This course is job oriented and aims to impact practical skills on how to use GIS and RS ,to overcome the major challenges faced in ,pre-disasters during disaster and post-disaster management such as during early warning, hazard, vulnerability and risk assessment, damage assessment, as well as in the design of risk reduction measures. DURATION 5 Days TARGETED AUDIENCE The course is targeted at professionals who require knowledge and skills on the use of GIS and RS in their organization in the field of disaster management.

  10. Event: GIS and Remote Sensing for Epidemiology and Public Health Course Venue: Indepth Research Services, Nairobi, Kenya. Event Date: 11th – 15th June 2018. NITA CERTIFIED RECENT CLIENTS INTRODUCTION Epidemiology seeks to determine associations between exposure risk and disease that are spatially dependent. Public health focuses on the health of populations rather than of individuals and focuses more on prevention of health problems. These efforts fall naturally within the domain of problems requiring use of spatial analysis as part of the solution, and GIS and other spatial analysis tools are therefore recognized as providing potentially transformational capabilities for Epidemiology and public health efforts. Statistics are a mainstay in the toolkit of public health professionals. Human memory being what it is, however, even Public health professionals with reasonable statistical training, over the years, often forget the basics. If professionals are going to make sensible use of consultants, communicate effectively with funders, and understand others’ reports, then they often need at least a conceptual understanding of relatively complex, recently developed statistical techniques. This course are: to link common public health questions with appropriate statistical procedures; to offer a strong conceptual grounding in several important statistical procedures; and to describe how to interpret the results from the statistics in ways that are principled and will be persuasive to intended audiences using simple software tools. Participants will acquire hands-on skills in use of Geographic Information System (GIS) as a tool to capture, store, analyze, manage, and visualize disease cases data that is geographically linked. The participants will also acquire statistical data analysis skills. WHO SHOULD ATTEND? The course is targeted at individuals working with health data that have no experience using GIS but would like to learn how it can be applied in their work. COURSE OBJECTIVES · To develop Understanding on the different components of a GIS and the role GIS plays in solving epidemiological and public health problems. · To present to participants all data-related aspects of a GIS, such as the data models in GIS, data input, data editing, data visualization, metadata and managing a spatial database. · To Carry out advanced analyses of geographical data with specific reference to epidemiological related issues · To improve data management and analysis skills of the participants · To perform spatial and temporal epidemiological and public health analysis using GIS. · Establish understanding on how to work with spatial data and GIS techniques to solve epidemiology and public health problems. · To expose participants to data capture, input, manipulation and display by GIS · To demonstrate to participants use of GIS in mapping health facilities and projects. · To explain to the participants role of GIS as a decision support system in public health TOPICS TO BE COVERED The training workshop will discuss the application of GIS in Public Health under the following themes: · Epidemiology and public health concepts and frameworks · GIS data management in epidemiology and public health. · Spatial mapping and Visualization in Epidemiology and Public health · GIS for monitoring in Epidemiology and public health · Participatory GIS in public health · Use of mobile GIS in health surveillance and assessments · Integrating GIS into Electronic Medical Records (case studies or practical?) · Basic statistical data analysis for Epidemiology and Public health · Graphs and Charts Line Graphs Visit our website for more details How to participate · Tailor Make a Course · Register individual. · Register as a group. · Become One of Our Partners. · Purchase software’s · Frequently Asked Questions (FAQs) View related courses GIS and Remote Sensing For Climate Change Impact Analysis and Adaptation Course GIS for Monitoring and Evaluation Course GIS for Monitoring and Evaluation Course GIS and remote sensing in multi hazard early warning systems Course The most popular courses · Resilience in Food Security Analysis Course · Introduction to Occupational Health and Safety Course · Analysis of Complex Sample Survey Data Course · M & E, Data Management & Analysis for Agriculture & Rural Development Programmes Course · Microsoft Access Training Course · ICT for Disaster Response Course · Change Management Course View GIS and Earth Observation Institute Course Catalogue For further inquiries, please contact us on Tel: +254 715 077 817, +254 (020) 211 3814 ACCOMMODATION Accommodation is arranged upon request.

  14. NDVI images with Sentinel 2

    @ASalas Also adding to pasfans01 answer 2., keep in mind that if you want to use NDVI for data assimilation puproses (e.g. compute vegetation biophysical parameters etc.) you will need the Surface Reflectance (Level 2A) data to produce the NDVI map, since 2A are more close to the true radiance values. For more information, you could read the sentinel 2 users guide that ESA offers. If you use the 2A data, in your case it would be of great help to first check the quality assesment data in order to see and assess the impact of cloud coverage in you scene. Regards

  16. Help with Landsat ARD Metadata?

    The .MTL.txt is a text file and the ARD .xml is an XML. You cannot just change the extension and expect an xml schema to be parsed like the text file. Harris has not developed a parser for this yet, but they will likely do it in the future just like reading in Sentinel-2 .xml. In the mean time, you can simply develop your code in IDL to parse the XML file and pull the metadata of interest. Those parameters can be used in an ENVITask workflow chain. I had to do this when the Collection-1 MTL changed from the original and broke the ENVI parser. The GeoTiFF itself will open like any other image.

  23. Where to sell GIS related Domain?

    Selling contents like data and software which are not yours are very illegal. In 2018 its a waste of time, even if those are yours. If you have quality contents which you think might help others, you should make an online service and sell those to other companies. In that way your contents will remain yours, but people will still get benefitted. Otherwise, get an authentication that the data is yours (ie. a research article may be) and then put everything into public domains. Sooner or later someone else will do the same and steal the spotlight which might be yours.
  24. Hi, I have the domain shpfile.com & was wondering where would be a good place to sell it? I don't have the time unfortunately, but I wanted to create a website to a list of shp files people could download. If anybody is interested in it, I am looking to get $20 for it. Please let me know where would be a good place to list this. Thank you all.
  25. Hello, Can anyone tell me how can I calculate "Weighted Absorption Centre (WAC)'' at the pixel level in multi-spectral data using ENVI/ERDAS/QGIS/E-cognition?
  26. Hi! I am downloading some data from https://earthexplorer.usgs.gov/. I am using that data to create DEM map, grayscale maps for use in games, 3d programs for landscape design. The problem is: I crop area in GlobalMapper - Edit - export (geoTiff) -export elevation grid - export bounds- draw box - i use shift so x,y axis are same sized,.. then I save that image. If I open the image in Photoshop, x,y axis have same pixel size, seem same length, or width. On the other hand If I open them in GlobalMapper or Microdem, x,y axis seem same on screen. but when I select measure tool and measure x and y axis, are different. WTF??? Example 4096 * 4096 pixel resolution map, but x axis is measured 35 km, and y axis 45 km??? My primary field is 3d graphics, so you have to excuse me if it is beginner question. tools- configure - projection is geographic. I want the same sized map - so if the map is sized 4096 * 4096 pixel and it also represents same proportions in real world (x,y axis are same sized in ft or km) Another example: https://ibb.co/iXh8cH https://ibb.co/nMhPHH Dem map size is the same in pixels but not in kilometers. What is the issue?
  27. Build Orthomosaic in Global Mapper 19.1

    I think you have better luck using a Photogametry softwares like 3DZephyr, Pix4d , or Photoscan than global mapper.
