This is a free resource, an attempt to make a government service more available, and I don&#8217;t make any money from it.)<\/p>\n<p>Howdy folks,<\/p>\n<p>I wanted to share a project I&#8217;ve been working on, called <strong>Lance-TS<\/strong>.<br \/> It&#8217;s an opinionated TypeScript client for the <a href=\"https:\/\/geocoding.geo.census.gov\/geocoder\/\">U.S. Census Geocoder API<\/a>, which is a free resource for geocoding U.S.-based addresses based on the <a href=\"https:\/\/www.census.gov\/geographies\/mapping-files\/time-series\/geo\/tiger-geodatabase-file.html\">TIGER\/Line<\/a> census geospatial database. It has no posted rate limits that I can find, and handles single and batch-address geocoding. Currently it handles address-to-coords, and I&#8217;ll implement coordinates-to-geography shortly.<\/p>\n<p>My repo for this tool is attached, and the package can be installed from the npm registry with:<\/p>\n<pre><code>npm i lance-ts pnpm add lance-ts yarn add lance-ts <\/code><\/pre>\n<p>Happy Geocoding! I&#8217;ve been working with map data a lot as I build some a platform for my company, and thought I would make this resource easy to access for more people. <\/p>\n<p>Kindly submit any issues or edge cases you encounter while using LANCE, and I will fix them ASAP. Cheers! <\/p>\n<\/div>\n<p><!-- SC_ON -->   submitted by   <a href=\"https:\/\/www.reddit.com\/user\/Fredrickjonjones\"> \/u\/Fredrickjonjones <\/a> <br \/> <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1u59p8j\/lancets_a_free_usaddress_geocoding_library\/\">[link]<\/a><\/span>   <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1u59p8j\/lancets_a_free_usaddress_geocoding_library\/\">[comments]<\/a><\/span><\/p><div class='watch-action'><div class='watch-position align-right'><div class='action-like'><a class='lbg-style1 like-41377 jlk' href='javascript:void(0)' data-task='like' data-post_id='41377' data-nonce='72e055e984' rel='nofollow'><img class='wti-pixel' src='https:\/\/www.graviton.at\/letterswaplibrary\/wp-content\/plugins\/wti-like-post\/images\/pixel.gif' title='Like' \/><span class='lc-41377 lc'>0<\/span><\/a><\/div><\/div> <div class='status-41377 status align-right'><\/div><\/div><div class='wti-clear'><\/div>","protected":false},"excerpt":{"rendered":"<p>Project Link (Not self-promotion, unless you count open-sourcing a tool as self promotion.
