For example, it can answer questions such as: <em>where are disease rates higher or lower? How far is the nearest healthcare facility? Where to deliver vaccines in order to reach \u201czero-dose children\u201d<\/em>?<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>As with all data, geospatial data can be wrong. And with all data, clean data is needed for good analyses.<\/strong> Wrong location information can lead to wrong orientation of resources, while wrong boundaries can lead to wrong estimation of aggregated information which can alter epidemiological insights.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong><a href=\"https:\/\/www.bluesquarehub.com\/expertise\/precision-public-health\/georegistry-microplanning-tools\/\">In the context of our work across over 20 LMICs (mostly in Africa), Bluesquare handles a lot of geospatial data<\/a><\/strong>: from helping Ministries elaborate master facility lists to integrating spatialized climate data into malaria surveillance tools, to improving the alignment of health area boundaries to new administrative realities<strong>. We are confronted every day with the issues linked to incorrect and incoherent data. It seems important to us that local actors get a better feeling for the impact this can have, what to watch out for when evaluating spatial data and how to go about fixing some of the most obvious issues<\/strong>. This is what this webinar is about.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">More concretely, during this webinar,&nbsp; we will first provide an overview of different use cases for geospatial data and how data errors influence the results of the analyses in these cases. We will then present three specific examples linked to three types data and of incoherences, showing for each type how to assess the quality and which tools and approaches to use to fix the most common errors:<\/p>\n\n\n<ul class=\" wp-block-list eplus-wrapper eplus-styles-uid-9a422b\">\n<li class=\" eplus-wrapper\"><strong><em>Point data<\/em><\/strong> such as health facilities, schools, etc: how can we verify location quality, and what types of errors can we identify?<\/li>\n\n\n\n<li class=\" eplus-wrapper\"><strong><em>Single polygon<\/em><\/strong> <em><strong>layer<\/strong><\/em> such as administrative boundaries, health areas, etc: how can we identify internal errors to such a layer, even if they are not easily visible to the naked eye?
