Installation
12
+
------------
13
+
14
+
To install CanCurve, you first need to install QGIS, then you can install CanCurve from the Plugin Repository.
15
+
16
+
For detailed instructions, refer to the `project README <https://github.com/NRCan/CanCurve/tree/main?tab=readme-ov-file#installation>`_.
17
+
For best performance, ensure you have the specified version of QGIS installed.

Overviews
23
+
-----------------------
24
+
CanCurve is a collection of tools for generating Depth Damage Functions (DDF) used by platforms like `CanFlood <https://github.com/NRCan/CanFlood>`_ to create flood risk models.
25
+
CanCurve's :ref:`Buildings Tool <sec02-bldgs>` for example facilitates the creation of DDFs from detailed restoration cost data for archetypal buildings.
26
+
This tool joins a table of restoration activities (e.g., repair dry-wall for $1000), called the :ref:`Cost-Item Table <sec02-costItem>`, to a database of information on the flood vulnerability of those items, called the :ref:`Depth-Replacement-Factor (DRF) Database <sec02-DRF>`.
27
+
After identifying the target building or archetype for which a user would like to construct a DDF, typically a :ref:`Cost-Item Table <sec02-costItem>` is prepared using local pricing tables and expert knowledge on the restoration of the building.
28
+
For the :ref:`DRF Database <sec02-DRF>`, either the version shipped with CanCurve can be used (default), or an alternate file can be specified.
29
+
Once these inputs and the building metadata are prepared and entered into the Buildings Tool, the four :ref:`Curve Creation <sec02-Core>` steps can be run to create and export a DDF in :ref:`CanFlood format <sec02-CanFloodFormat>`.

Quick-Start
38
+
-----------------------
39
+
After installation of the plugin, the |CanCurve_icon| icon should appear on your plugins toolbar.
40
+
If you don't see the icon, first ensure the plugin is checked on the **Installed** tab of the **Manage and Install Plugins..** dialog; then ensure the **plugins toolbar** is enabled by right-clicking the QGIS toolbar.

To start working with CanCurve, click the |CanCurve_icon| to open the :ref:`Buildings Tool <sec02-bldgs>` dialog.

+

+
59
+
To use the tool to create a DDF from data for your archetypal building, first populate the **Metadata** tab with whatever information is available (see the :ref:`Tutorials <sec03-tutorials>` section for example data).
60
+
Note only fields marked with an asterisk (*) are required, but the more information you provide, the more complete your DDF will be.
61
+
To specify settings, the :ref:`Cost-Item Table <sec02-costItem>`, the :ref:`Depth-Replacement Factor (DRF) Database <sec02-DRF>`, and the :ref:`Fixed Costs <sec02-fixedCosts>` data, complete the **Data Input** tab.
62
+
Finally, the four curve creation steps can be executed from the **Create Curve** tab, ending in an export of your DDF in :ref:`CanFlood format <sec02-CanFloodFormat>`.
63
+
64
+
65

See the :ref:`User Guide <sec02-userGuide>` and the :ref:`Tutorials <sec03-tutorials>` section to learn more.

Frequently Asked Questions
71
+
--------------------------
72
+
73
+
**Where can I find Cost-Item data for my archetype?**
74
+
Typically this information is obtained from cost restoration experts using specialized software like Xactimate and a detailed model of the structure.
75
+
76
+
**How can I add entries to my Depth-Replacement-Factor (DRF) Database**
77
+
You'll need to use some software that allows editing of SQLite databases. We recommend `DB Browser for SQLite <https://sqlitebrowser.org/>`_.
78
+
79
+
**Where can I go to get help?**
80
+
The best place to get help is the `CanCurve GitHub Issues <https://github.com/NRCan/CanCurve/issues>`_ page where you can read through questions posted by others or ask your own.
81
+
82
+
83
+
**Do I really need to install an old version of QGIS to use CanCurve**
84
+
No, but we recommend it for best performance. If you have a newer version of QGIS installed, you can try CanCurve with it, but you may experience issues.
