Siting locations for a sandbag wall<\/h3>\n
Determining the location of a sandbag wall is usually best estimated in the field.\u00a0 Local relief, soil composition, and other factors can influence where to construct a sandbag wall for maximum effect.\u00a0 Using Field Maps or Collector, field workers can evaluate various sites and capture where they want to place the sandbag wall by walking the desired location and collecting a line feature using their GPS.\u00a0 In addition, they can capture other information about the proposed wall, including the desired height of the wall and the type of construction.<\/p>\n
Here’s an example of a line captured in Collector with some basic attribution to define the key characteristics of our sandbag wall.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":601992,"id":601992,"title":"SandbagWallCollectInit","filename":"SandbagWallCollectInit-e1567727179115.jpg","filesize":49925,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/SandbagWallCollectInit-e1567727179115.jpg","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/field-maps\/field-mobility\/estimate-materials-sandbag-wall\/sandbagwallcollectinit","alt":"","author":"8072","description":"","caption":"","name":"sandbagwallcollectinit","status":"inherit","uploaded_to":582092,"date":"2019-09-05 23:44:53","modified":"2019-09-05 23:44:53","menu_order":0,"mime_type":"image\/jpeg","type":"image","subtype":"jpeg","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":400,"height":865,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/SandbagWallCollectInit-213x200.jpg","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/SandbagWallCollectInit-e1567727179115.jpg","medium-width":121,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/SandbagWallCollectInit-e1567727179115.jpg","medium_large-width":400,"medium_large-height":865,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/SandbagWallCollectInit-e1567727179115.jpg","large-width":400,"large-height":865,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/SandbagWallCollectInit-e1567727179115.jpg","1536x1536-width":400,"1536x1536-height":865,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/SandbagWallCollectInit-e1567727179115.jpg","2048x2048-width":400,"2048x2048-height":865,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/SandbagWallCollectInit-215x465.jpg","card_image-width":215,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/SandbagWallCollectInit-500x1080.jpg","wide_image-width":500,"wide_image-height":1080}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"
Estimating materials<\/h3>\n
Once the location of the sandbag wall is defined along with the desired wall height we can calculate the necessary materials.\u00a0 We’ll use the following information we captured in Collector:<\/p>\n
- \n
- Desired wall length<\/strong> – we’ll use the geometric length of our proposed sandbag wall.<\/li>\n
- Desired wall height<\/strong> – captured as an attribute of our proposed wall.<\/li>\n
- Wall type<\/strong> – captured as an attribute of our proposed wall.<\/li>\n<\/ul>\n
There are two basic types of sandbag walls: a single stacked row of sandbags, or a staggered wall called a dike.\u00a0\u00a0Based on the type of wall, different amounts of material are required to build the same size wall. We’ll need to have two different Arcade expressions that can be used to calculate materials based on the type of wall.<\/p>\n"},{"acf_fc_layout":"content","content":"
Estimating materials for a single stack wall<\/h3>\n
Let’s start with estimating the material needed for a single stack sandbag wall.<\/p>\n
First, we need to determine the number of sandbags using the following Arcade expression.<\/p>\n

This is our initial attempt at gauging interest among users and developers to see how sharing common Arcade expressions can ease some of your workflows.\n\nAt the time of this blog post, there are only four expressions included in the repo. Each is thoroughly documented so you can copy and paste the template into the Arcade editor in ArcGIS Online (or in your custom apps) and set the appropriate values and field names that match your dataset.\n\nIf you're unfamiliar with Arcade check out the following resources:\n\n

- Esri guidelines for contributing to GitHub repositories<\/a><\/li>\n<\/ul>\n\nTo contribute, simply fork the repo, clone it locally to your machine, and add a new Markdown file describing the expression. Follow the same format as the existing expressions, providing others with a well documented template they can copy and paste easily into their apps. Also be sure to provide a completed example showing how the expression works for the given profile with a real dataset. Once that is done, submit a PR so your expression can be shared to the world.\n\n[embedyt] http:\/\/www.youtube.com\/watch?v=aI8HkAkUXuY[\/embedyt]\n\nThe goal of this repository is to encourage collaboration and allow everyone to benefit from others\u2019 creativity in using Arcade for solving real problems.
