07 Setting conditions on the map

v0.x〜

In step 3 of Add analysis, 地図上で条件を設定 (Set conditions on map) opens a full-screen map editor. What you set on the map depends on the analysis. This chapter covers each analysis in turn, then the building tools every analysis shares.

What each analysis needs on the map

Analysis	Set on the map	Required	Optional	確定 (Confirm) is enabled when
Ground shadow	Analysis area (rectangle)	Area	Add, exclude buildings, IFC	The area is 25 ha or less
Wall shadow	Buildings to check	At least one building	Add, exclude buildings, IFC	At least one building is selected
Noise	Area and noise sources	Area, one or more sources	Barriers, add, exclude buildings, IFC	Area is 25 ha or less and there is a source
Wind	Centre point and wind	Centre point	Add, exclude buildings, IFC	There is a centre and the inputs are valid

The screen

• Left panel: what you have set (area coordinates, chosen buildings, sources, added and excluded buildings and so on).
• Tool buttons at the top left of the map: switch tools. Which buttons appear depends on the analysis.
• Hint at the top of the map: how to use the current tool.
• 確定 at the top right: sends what you set back to Add analysis. Nothing is calculated yet; that starts with 計算開始 (Start calculation) on the main screen.
• × at the top left: closes without confirming; what you set on the map is not applied.

Ground shadow: draw the area

The tools are 解析範囲 (Extent), 建物追加 (Add buildings), 建物除外 (Exclude buildings) and IFC. The extent tool is selected when the editor opens.

1. Press 範囲作成 (Create area) and click-and-drag a rectangle on the map.
2. Drag inside the rectangle to move it, a corner to resize it, or the rotation handle to rotate it. To set an exact angle, type it in 角度 (Angle) and press 回転 (Rotate).
3. The size is shown as "Area: X ha". Above 25 ha it turns red with "⚠ Exceeds maximum area!". 確定 is then disabled, so keep it within 25 ha.
4. 範囲リセット (Reset area) starts over.

The coordinates of the area are shown, but you cannot create the area by typing numbers.

Once drawn, the area is marked 設定済み (set) and its size is shown.

The target building area, where buildings casting shadows are collected, is set automatically: the analysis area widened by 100 m on every side. Shadows from buildings outside it are not computed.

Wall shadow: choose the buildings

You don't draw an area. The tools are 予測対象建物選択 (Select target building), Add buildings, Exclude buildings and IFC Upload.

1. Choose 予測対象建物選択 and click the buildings to check. Selected buildings turn orange; click again to deselect.
2. To check a planned building, draw it first with Add buildings, then make it a target from the 新規 (New) list.
3. Selected buildings are listed under 選択済み建物 (Selected buildings), tagged Existing or New. The bin icon removes one; クリア (Clear) removes all.
4. Once at least one building is selected, 確定 is enabled.

Target buildings turn orange and are listed under 選択済み建物 on the left.

The analysis area is set automatically around the selected buildings. A building chosen as a target cannot be excluded.

Noise: area, sources and barriers

The tools are Extent, 騒音源 (Noise sources), Add buildings (optional), Exclude buildings (optional), 遮音壁 (Barriers) and IFC. The other tools stay disabled until the area is drawn. Set things in this order:

1. Area: draw a rectangle as for ground shadow (drawing the area). Above 25 ha, 確定 is disabled.
2. Noise sources: place at least one (below).
3. Barriers: place them if needed (below).
4. Add, exclude buildings, IFC: if needed (shared tools).

Placing noise sources

The first time you choose 騒音源 you pick the source type. All sources in a case are the same type.

Construction machinery

Sources based on the Acoustical Society of Japan construction noise model (ASJ CN-Model 2007). Choose a machine from the list.

General

Set the sound power level and height freely. You also set the centre frequency.

Choose the source type first.

Changing the type later (騒音源タイプを変更, Change noise source type) deletes every source already placed.

Click the map to place a source; its settings open. Clicking a rooftop adds the roof height.

Item	Allowed	Meaning
Select machinery	From the list	Type of machine; sets the sound power level and height
Sound power level (Lw)	0.1–200 dB	How loud the source is. Default 100 dB for General
Height above ground	0–999 m	Height of the source. Default 1.5 m
Coordinates (lon, lat)	—	Position; you can also drag it on the map

Placing a source opens its settings on the right and lists it on the left.

Machinery and sound power levels:

Machine	Lw
Bulldozer	105 dB
Backhoe	106 dB
Crawler crane	107 dB
All-casing drilling machine	107 dB
Road roller	104 dB
Asphalt paver	107 dB
Concrete pumping vehicle	107 dB
Concrete mixer truck	100 dB
Dump truck	102 dB (height 0 m)
Others	Set your own

With a listed machine, Lw and height are fixed. Choose その他 (Others) to enter them yourself and to pick construction machinery or construction vehicle.

保存 (Save) confirms and キャンセル (Cancel) reverts. Placed sources can be edited or deleted from the list on the left.

Placing noise barriers

1. Choose 遮音壁 and press 新しい遮音壁の作成 (Create new barrier).
2. Click points along the wall on the map (two or more). Drag a point to move it; click it to remove it.
3. Right-click or press 確定 (Finish).

The wall grows as you add points; the toolbar shows the point count.

Each point is 2 m high by default; clicking a rooftop adds the roof height.

To edit later, click the wall on the map or the pencil icon in the list.

Move point

Drag a point. Drag a segment midpoint to add a point. Click a point to change its height.

Move whole barrier / Rotate

Move the wall as a whole, or drag the ring to rotate it.

Delete point

Click a point to remove it (minimum two).

Point heights

Enter a value in 一括高さ設定 (Uniform height) and press 全点に適用 (Apply to all points) to give every point the same height (0.1–999 m), or set each point separately.

Wind: centre point and wind

You pick a centre point instead of drawing an area. The tools are 中心 (Center), Add buildings, Exclude buildings and IFC. The wind conditions are also set in this screen's left panel.

1. Choose 中心 and click the centre of the analysis on the map, or type it into Center longitude and Center latitude on the left.
2. A 200 m square around it (cyan) and an arrow for the wind direction appear. The square turns with the wind direction.
3. In the left panel, set wind direction, wind speed, reference height, receptor height and roughness category. See wind conditions for what each means.
4. Add, exclude buildings or bring in IFC if needed, then press 確定.

After choosing the centre, the 200 m square (cyan) and the wind arrow appear. Set direction, speed and so on on the left.

Pressing 確定 without a centre asks you to click the map to choose one. If there is no building data within 200 m of the centre, "No building data" appears; pick a place with PLATEAU data or add buildings. A detailed guide is under 操作ガイド（PDF） (Guide, PDF) at the top right.

Adding planned buildings

Draw buildings that don't exist yet and include them in the analysis.

1. Choose 建物追加 (Add buildings) and enter 建物の高さ (building height, 1–500 m, default 10 m).
2. Press 描画開始 (Start drawing) and click the building's corners on the map in order.
3. After three or more points, right-click or press 確定 (Finish). An outline whose walls cross is rejected with "The building walls intersect".

Added buildings are listed as "Building 1", "Building 2"…, and their height can be changed in the list. To reshape one, click it on the map or press the pencil icon in the list.

Move vertex

Drag a vertex. Drag an edge midpoint to add a vertex.

Move all

Drag the centre handle to move the whole building.

Rotate

Drag the rotation handle.

Delete vertex

Click a vertex to remove it (minimum three).

Adjust height

Drag the green handle up or down.

Press 完了 (Done) when finished. The bin icon deletes a building straight away, without asking.

Editing an added building. The toolbar at the bottom switches between move vertex, move all, rotate, delete vertex and adjust height.

Excluding existing buildings

Leave out buildings that will be demolished, for example.

1. Choose 建物除外 (Exclude buildings) and click buildings on the map. Excluded buildings turn translucent.
2. Click again to bring one back.

Excluded buildings are listed; the bin icon restores one and クリア (Clear) restores them all. In wall shadow, a building chosen as a target cannot be excluded.

Excluded buildings turn translucent and are counted under 建物除外 on the left.

Using an IFC building

Bring a building you are designing into the analysis from IFC.

1. Choose IFC. For a new file, pick an .ifc on the 新規アップロード (New upload) tab; for one already in the project, use 既存データから (From existing data).
2. Choose the detail level. LOD1 (simple block) brings the building in as one block; LOD2 (per storey) keeps the shape of each storey.
3. Press 解析 (Parse). Progress shows "Loading IFC…" and "Analyzing geometry… %", then 3D previews of the original and the imported shape appear side by side; drag to orbit. Height and building count (and storeys for LOD2) are shown.
4. Place it. If a position was saved, choose 保存された位置 (Saved position) or 地図でクリック (Click on map); otherwise click the map.

Buildings imported as LOD2 can only be moved and rotated, not reshaped or raised. やり直す (Start over) begins again.

The IFC panel: choose a file, pick LOD1 or LOD2, then press 解析 (Parse).

If no building shape is found, "Could not detect any building geometry in the IFC file" appears. How to export IFC from Revit, Civil 3D or AutoCAD is explained under "マニュアル・ドキュメント" (Manuals) on the product home page.
